摘要： A wireless communication receiver improves signal impairment correlation estimation in MIMO/MISO systems by considering different transmit power allocations and different transmit antenna power distributions in its impairment correlation calculations. The receiver may be implemented in according to a variety of architectures, including, but not limited to, Successive Interference Cancellation (SIC) Generalized RAKE (G-RAKE), Joint Detection (JD) G-RAKE, and Minimum Mean Squared Error (MMSE) G-RAKE. Regardless of the particular receiver architecture adopted, the improved impairment correlations may be used to calculate improved (RAKE) signal combining weights and/or improve channel quality estimates for reporting by receivers operating in Wideband CDMA (W-CDMA) systems transmitting HSDPA channels via MIMO or MISO transmitters. A transmitter may be configured to facilitate impairment correlation determinations by wireless communication receivers operating in MIMO/MISO environments, by signaling one or more values, e.g., data-to-pilot signal transmit power ratios and/or transmit antenna power distributions for the data and pilot signals.

摘要： A method is described herein that enables a Selective-Per-Antenna-Rate-Control (S-PARC) technique to be effectively implemented in a wireless communications network (e.g., HSPDA third generation communications network). In one embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a “full” feedback signal to a base station that analyzes the “full” feedback signal and determines which mode and transmission rate(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device. In another embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a “reduced” feedback signal to a base station that analyzes the “reduced” feedback signal and determines which mode and transmission rate(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device.

摘要： A receiver includes a receiver circuit that decodes multiple signals of interest contained in a composite received signal. The receiver comprises a plurality of successive signal detection stages to detect respective signals contained in the composite received signal. Each detection circuit comprises at least one Generalized RAKE combining circuit and generates a detected signal at an output. Each but the last stage further comprises a signal regeneration circuit that cancels the signal of interest detected by that stage from a stage input signal provided to the next stage such that successive detection of the signals of interest benefits from cumulative cancellation of the previously detected signals.
