| 20090034588 | METHOD AND APPARATUS TO PROCESS DEDICATED PILOT BITS FROM MULTIPLE FINGERS - A method to process DP bits from multiple fingers within a WCDMA rake receiver is provided. DPCH pilot symbols are received, quantized and channel compensated. Then processing operations for individual fingers for the channel compensated quantized despread DPCH pilot symbols are chosen based on the DPCH slot format. The DPCH pilot symbols are processed based on the DPCH slot format in order to produce processed DPCH pilot symbols in a common format. These processed symbols may then be combined. Other embodiments may further allow for the computation of an SNR estimate based on the combined DPCH pilot symbols. | 02-05-2009 |
| 20090036081 | METHOD AND APPARATUS TO PROCESS DEDICATED PHYSICAL CONTROL CHANNEL (DPCCH) IN A TRANSMIT ANTENNA DIVERSITY (TXDIV) RAKE FINGER - A method to process DP bits and TPC bits from multiple fingers within a WCDMA rake receiver is provided. DPCH symbols are received, quantized and channel compensated. Then processing operations for individual fingers for the channel compensated quantized despread DPCH symbols containing DP bits and TPC bits are chosen based on the DPCH slot format. The DPCH symbols are processed based on the DPCH slot format in order to produce processed DPCH pilot symbols in a common format. DP bits and TPC bits may be processed in parallel by separate processing branches or in series by applying timing control to common processing modules. These processed symbols may then be combined. Other embodiments may further allow for the computation of an SNR estimate based on the combined DPCH symbols. | 02-05-2009 |
| 20090036117 | WIRELESS DEVICE OPERABLE TO MANIPULATE HIGH-SPEED SHARED CONTROL CHANNEL (HSSCCH) QUALITY CONTROL THROUGH CHANNEL QUALITY INDICATION REPORT MANIPULATION - A method to adapt channel quality indicator (CQI) reports from user equipment (UE) is provided. This involves first determining the presence of a high-speed shared control channel (HS-SCCH) signal. An estimated signal to noise ratio (SNR) is also determined. Next an SNR correction based on the presence or lack thereof of the HS-SCCH signal and the CRC checks for HS-SCCH and HS-DSCH signals are determined and applied to the estimated SNR. The CQI report is then generated based on the corrected estimated SNR. This CQI report which takes into account a corrected estimated SNR may then be used to adjust the HS-SCCH signal in an HSDPA telephony system. | 02-05-2009 |
| 20090233567 | WEIGHT GENERATION METHOD FOR MULTI-ANTENNA COMMUNICATION SYSTEMS UTILIZING RF-BASED AND BASEBAND SIGNAL WEIGHTING AND COMBINING - A method for processing signals is disclosed and may include performing using one or more processor and/or circuits in a receiver that uses a plurality of antennas: receiving via a channel, a plurality of RF signals by one or more of the plurality of antennas. The plurality of received RF signals may be weighted utilizing one or more corresponding RF weighting values to generate a plurality of weighted RF signals. The one or more corresponding RF weighting values may include a frequency-independent weight coefficient that is constant over the channel. At least a portion of the plurality of weighted RF signals may be combined to generate one or more combined RF signals. The one or more corresponding RF weighing values may be selected to maximize an output signal-to-noise ratio of the channel. The output signal-to-noise ratio may be averaged over the channel. | 09-17-2009 |
| 20090238310 | WEIGHT GENERATION METHOD FOR MULTI-ANTENNA COMMUNICATION SYSTEMS UTILIZING RF-BASED AND BASEBAND SIGNAL WEIGHTING AND COMBINING BASED UPON MINIMUM BIT ERROR RATE - A method for processing communication signals is disclosed and may include, in a receiver and/or a baseband processor coupled to the receiver, the receiver comprising a plurality of antennas, generating a plurality of RF weighting values based on one or more output bit error rates of the receiver. A plurality of spatially-multiplexed RF signals, which are received by the receiver, may be weighted with the one or more of the generated plurality of RF weighting values, to form a plurality of weighted RF signals. Two or more of the generated plurality of weighted RF signals may be combined to form one or more combined RF signals. Each of the one or more combined RF signals may be processed by a different RF processing chain. The one or more output bit error rates of the receiver may be minimized by the generation of the plurality of RF weighting values. | 09-24-2009 |
| 20110096860 | Multi-Antenna Communication Systems Utilizing RF-Based and Baseband Signal Weighting and Combining - A receiver operatively coupled to an antenna structure capable of receiving a first plurality of RF signals is disclosed herein. The receiver includes an RF processing network operative to perform weighting and combining operations within the RF domain using the first plurality of RF signals so as to produce a second plurality of RF signals. Also provided is a downconverter configured to downconvert the second plurality of RF signals into a second plurality of down-converted signals. In alternate implementations certain of the weighting and combining operations are performed at baseband and the remainder effected within the RF domain. A transmitter of corresponding architecture is also disclosed. | 04-28-2011 |
