摘要： Methods and apparatus for control signaling in a communication system using continuous valued measurement and feedback are disclosed. The control signaling utilizes delta-sigma modulation where a measured phase or amplitude of a received signal is used to determine a difference signal by subtracting a previously quantized integrated difference signal from the current measurement signal, and then integrating the difference signal. The integrated difference signal is quantized and transmitted to the device originating the received signal as feedback control signaling. The device originating the received signal may then filter the control signaling to obtain the desired control information used to adjust or control the transmission of the signal transmitted by the device. By utilizing delta-sigma modulation, a greater degree of control signaling precision is achieved when controlling variables such as phase or amplitude of the transmitted signals, thereby achieving improved communication system performance.

摘要： An apparatus, method, and computer program product operable to determine a phase of a beamforming weight vector utilizing a memory of a previously used phase for the beamforming weight vector, capable of improving a channel estimate. A base station (320) transmits a beamforming weight vector to a user equipment (310) based on a determined channel estimate. The user equipment (310) selects between the received beamforming weight vector, or a modified beamforming weight vector having its phase shifted by -360, in accordance with a suitable selection criteria. That is, the selection is made such that a difference between the phase of the selected beamforming vector and a phase of a prior beamforming vector is within a predetermined range.

摘要： Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

摘要： A base station receiver (610), a computer program product operable at a base station (600), and a method operable at a base station receiver (610), for receiving uplink transmit diversity transmissions utilizing a master / slave scheme at the receiver (610). One or more tracking loops, such as a searcher task, a time tracking loop, or a frequency tracking loop may be implemented at the base station receiver (610) to determine compensation values, such as finger timings for a rake receiver or frequency compensation values, in accordance with characteristics of a primary pilot channel (514) transmitted utilizing a first precoding weight vector. Here, corresponding compensation values may be derived for the reception of a secondary pilot channel (520) transmitted utilizing a precoding weight vector orthogonal to the first precoding weight vector, simply based on those determined for the primary pilot channel (514). That is, the compensation value assignment for receiving the second pilot channel may act as a slave to its master, being the compensation value assignment for receiving the primary pilot channel (514).

摘要： Various embodiments include processing devices and methods for calibrating an image sensor of a robotic vehicle. The processor of the vehicle may obtain a test image. The processor may apply an adjustment matrix to the test image to produce a warped test image. The processor may identify test features of the warped test image. The processor may identify image features of the captured image and may compare the identified image features to the test features to find correspondences or matches. Using the correspondences to calculate the distortion between the warped test image and the captured image, the processor may generate homography matrix based, at least in part, on a result of comparing the identified image features to the identified test features. The processor may then determine a pose of the image sensor based, at least in part, on the generated homography matrix.
