| 20090285343 | SYSTEM AND METHOD FOR CANCELING INTERFERENCE IN A COMMUNICATION SYSTEM - A filter settings generation operation includes sampling a communication channel to produce a sampled signal. The sampled signal is spectrally characterized across a frequency band of interest to produce a spectral characterization of the sampled signal. This spectral characterization may not include a signal of interest. The spectral characterization is then modified to produce a modified spectral characterization. Filter settings are then generated based upon the modified spectral characterization. Finally, the communication channel is filtered using the filter settings when the signal of interest is present on the communication channel. In modifying the spectral characterization, pluralities of spectral characteristics of the spectral characterization are independently modified to produce the modified spectral characterization. Modifications to the spectral characterization may be performed in the frequency domain and/or the time domain. One particular spectral modification that is performed is raising of the noise floor of the spectral characterization to meet a budgeted signal-to-noise ratio. Other spectral modifications include modifying spectral components corresponding to an expected interfering signal. In modifying these spectral characterizations, spectral components corresponding to a plurality of expected interfering signals may be modified. | 11-19-2009 |

| 20090092153 | Downstream Synchronous Multichannels for a Communications Management System - Downstream synchronous multichannel (DSSM) communications are provided among a plurality of carriers, each being a completely DOCSIS™ 2.0-compliant downstream. The synchronous multichannels support communications with both DSSM-capable communications nodes and non-DSSM-capable communications nodes (e.g., legacy cable modems). Non-DSSM packets are transmitted on a single channel. DSSM packets are split into multiple pieces, which are transmitted simultaneously on all available channels. Since the physical delay variation (e.g., group delay change) across the adjacent carriers is small (on the order of a symbol time), the multiple pieces arrive at the receiving communications nodes at nearly the same time and can be reassembled with minimal buffering and no packet ordering problems. To avoid causing trouble for the non-DSSM-capable communications nodes, the packet pieces are encapsulated with a header that causes the non-DSSM-capable communications nodes to silently discard them. | 04-09-2009 |
| 20090215403 | Signal processing under attenuated transmission conditions - Signal processing under attenuated transmission conditions. Within an orthogonal signal space, the number of orthogonal signals that are used to transmit information from a transmitter to a receiver is reduced and the transmitted power of each of the now remaining orthogonal signals is modified; this may involve increasing the power of all of the remaining orthogonal signals equally or alternatively modifying them individually. The same modulation used before the reduction may also be used afterwards; within communication systems having multiple transmitter-receiver paths, this will ensure that the communication system's throughput and efficiency will remain unchanged even when one (or more) transmitter-receiver paths are highly attenuated. In addition, robust mode operation is provided for ranging and registering of transmitter devices when entering the communication system. In addition, the unused orthogonal signals may be employed to support interference cancellation of those orthogonal signals that are used to transmit information. | 08-27-2009 |
| 20090327845 | System and Method For Mitigating Burst Noise In A Communications System - A system, method and computer program product is provided for mitigating the effects of burst noise on packets transmitted in a communications system. A transmitting device applies an outer code, which may include, for example, a block code, an exclusive OR (XOR) code, or a repetition code, to one or more packets prior to adaptation of the packets for transmission over the physical (PHY) layer of the communications system, wherein the PHY layer adaptation may include FEC encoding of individual packets. The outer coded packets are then separately transmitted over a channel of the communications system. A receiving device receives the outer coded packets, performs PHY level demodulation and optional FEC decoding of the packets, and then applies outer code decoding to the outer coded packets in order to restore packets that were erased during transmission due to burst noise or other impairments on the channel. | 12-31-2009 |

| 20110074685 | Virtual Predictive Keypad - Devices and methods are disclosed which relate to improving the efficiency of text input by generating a dynamic virtual keyboard. Certain examples display a soft keyboard on a touchscreen of a text-entry device. The touchscreen works with the soft keyboard as a form of text input. Keyboard logic on the text-entry device is programmed to change the footprint of each key within the soft keyboard based on the prior entry. The keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next. The touchscreen displays a dynamic virtual keyboard based on these prediction values. Enhancements include resizing keys and their respective footprints relative to their prediction value. Other examples exploit the possible character sequences and their probabilities in a language and restructuring the keyboard to make text input more efficient. The devices and methods use modeling techniques to dynamically generate the size of the characters on the keyboard. | 03-31-2011 |
| 20110074686 | Angular Sensitized Keypad - Devices and methods are disclosed which relate to improving the efficiency of text input by measuring the angle of each key press and rejecting improbable keys pressed at an off-center angle. Examples include a text-entry device which has logic for resisting error while the user enters text on a keyboard of the text-entry device. Each key determines the angle at which the key is pressed. Keyboard logic on the text-entry device assigns a range of acceptable angles to each key. If a key is pressed within the range of acceptable angles, which is typically around the center, then the entry is permitted. If a key is pressed outside the range of acceptable angles, which is typically on the edges, then the entry is denied. Once text is entered, the keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next. The keyboard logic then adjusts the range of acceptable angles based on that statistical probability. | 03-31-2011 |
| 20110074691 | Predictive Force Sensitive Keypad - Devices and methods are described for improving the efficiency of text input by requiring more pressure to select keys on a dynamic keyboard that are improbable key presses. Examples include a text-entry device which has logic for resisting error while the user enters text on a keyboard of the text-entry device. Each key has a lever mechanism which varies the force required to press the key. Keyboard logic on the text-entry device is programmed to change the force required to enter each key within the dynamic keyboard based on the prior entry. The keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next. | 03-31-2011 |
| 20110074704 | Predictive Sensitized Keypad - Devices and methods are disclosed which relate to improving the efficiency of text input by generating a dynamic virtual keyboard. Disclosed examples display a soft keyboard on a touchscreen of a text-entry device. The touchscreen works with the soft keyboard as a form of text input. Keyboard logic on the text-entry device is programmed to change the sensitivity of the footprint of keys surrounding a predicted key or keys, based upon the prior entry. The keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next. The touchscreen displays a dynamic virtual keyboard based on these prediction values. Enhancements include reducing the sensitivity of the footprint of keys relative to their prediction value. For instance, if a key is very unlikely to be the next intended key pressed, the footprint of the key will only respond to a key press of greater force than a key which is likely to be entered next. | 03-31-2011 |
