20150244918 | METHOD AND CONTROL UNIT FOR CONTROLLING EXPOSURE OF A CAMERA - A method for controlling exposure of a camera is disclosed. The method comprises calculating a darkness level and a saturation level with respect to a first image in a video sequence. If the saturation level exceeds a first limit, a target value for a mean intensity value of pixels in images captured by the camera is decreased by an amount which is an increasing function of the darkness level. The decreased target value is used to control the exposure of the camera for images subsequent to the first image in the video sequence, such that the mean intensity value of pixels in the subsequent images approaches the decreased target value. | 08-27-2015 |

20090254598 | Folding of Input Data Values to a Transform Function - A method of processing a set of input data values comprises the steps of providing said input data values serially to circuitry comprising a number of memory elements; and performing in said circuitry a transform function to obtain a set of transformed data values. The method further comprises the steps of delaying a subset of said set of input data values under use of said memory elements; providing a modified set of data values by adding individual delayed data values to individual non-delayed data values from said set of input data values; and performing said transform function on said modified set of data values.

20110004775 | Methods and Systems for Use-Case Aware Voltage Selection - Systems and methods according to these exemplary embodiments provide for optimizing voltage use in digital circuits. This can be obtained by creating situations for digital circuits such that the effective critical path (ECP) can be used such as, for example, the case where a digital circuit includes a plurality of voltage domains powered by individual and possibly different voltage sources.

20110103497 | CHANNEL ESTIMATION IN OFDM RECEIVER EQUIPMENT - A receiver is operated so as to receive data conveyed on an Orthogonal Frequency Division Multiplexed (OFDM) signal transmitted on a plurality of sub-carriers. Such operation includes ascertaining which of the plurality of sub-carriers have a channel quality that satisfies one or more criteria. Then, sub-carriers are selected based at least in part on whether they have the channel quality that satisfies one or more criteria. The receiver then fully processes data streams only from the selected sub-carriers, wherein fully processing data streams comprises sub-carrier channel estimation or sub-carrier equalization or both sub-carrier channel estimation and sub-carrier equalization. | 05-05-2011 |
20110268232 | INTER-CARRIER BANDWIDTH CONTROL FOR MITIGATING IQ IMBALANCE - Digital IQ imbalance estimation and compensation is facilitated by shaping the frequency response of receiver branches. In particular, in a multi-carrier receiver, the frequency response of signal processing elements in at least one receiver branch is set to not fully attenuate received signals in a frequency band of interest. The frequency band of interest is greater than the carrier bandwidth of the received signal processed by that receiver branch. In some embodiments, the received signal is not attenuated, and adjacent interfering signals are partially attenuated. This allows information regarding the interfering signals to appear in an IQ imbalance-induced, inter-carrier image of the signals in anther receiver branch, facilitating digital estimation and compensation of IQ imbalance. | 11-03-2011 |

In some embodiments, a method for determining in-phase (I) and Quadrature (Q) imbalance (IQ imbalance) parameters based on a known signal in a dual-carrier receiver using at least one controllable frequency offset includes receiving a known signal modulated onto a first radio frequency (RF) carrier frequency and a second RF carrier frequency different than the first RF carrier frequency; downconverting the known signal to a baseband signal for the first and second carriers by conversion from the respective RF carrier frequencies to an intermediate frequency (IF) using a common RF local oscillator (LO) and by further conversion from IF to baseband using carrier specific IF LOs, wherein as a controllable frequency offset is used as a part of the conversion from at least one of RF to IF and IF to baseband through the LOs; removing any controllable frequency offset from the baseband signal for the first and second carriers to produce representations of the received signals of the first and second carriers; and deriving IQ imbalance parameters for each representation of the received signals of the first and second carriers using a least square estimate. | 07-05-2012 |
20130208776 | Test Signal in Receiver - The invention proposes a way of inserting an analog test signal during normal reception into analog blocks of an OFDM receiver in such a way that the reception is either not corrupted at all, or only very little. This is achieved either by inserting the analog test signal in time or frequency where it does not corrupt the received signal, or by accounting for the interfering analog test signal in the decoding process. | 08-15-2013 |
20130343492 | Controllable Frequency Offset for Inphase and Quadrature (IQ) Imbalance Estimation - Embodiments of user equipment and methods for determining IQ imbalance parameters are described. In some embodiments, a method for determining in-phase (I) and Quadrature (Q) imbalance (IQ imbalance) parameters based on a known signal in a dual-carrier receiver using at least one controllable frequency offset includes receiving a known signal modulated onto a first radio frequency (RF) carrier frequency and a second RF carrier frequency different than the first RF carrier frequency. The known signal is downconverted to a baseband signal for the carriers by conversion from the respective RF carrier frequencies to an intermediate frequency (IF) using a common RF local oscillator (LO) and by further conversion from IF to baseband using carrier specific IF LOs, where a controllable frequency offset is used. Any controllable frequency offset is removed from the baseband signal for the first and second carriers to produce representations of the received signals. | 12-26-2013 |
20140148112 | Technique and Test Signal for Determining Signal Path Properites - A test signal for determining a frequency-dependent or any other property of a receiver path is proposed. The test signal comprises, in a time domain representation, a sequence of discrete states that may be periodically repeated and that gives rise to a plurality of discrete tones in a frequency domain representation of the test signal. The test signal can be utilized for determining a frequency-dependent imbalance (e.g., an IQ imbalance) between different signal branches of a receiver or transmitter. | 05-29-2014 |
20140348272 | CONTROLLABLE FREQUENCY OFFSET FOR INPHASE AND QUADRATURE (IQ) IMBALANCE ESTIMATION - Embodiments of user equipment and methods for determining IQ imbalance parameters are described.
