Abstract: Certain aspects of the method may comprise generating at least one control signal that may be utilized to control at least a first of a plurality of received spatially multiplexed communication signals. An amplitude and/or phase of the first received spatially multiplexed communication signal may be adjusted via the generated control signal so that the amplitude and/or phase of the first received spatially multiplexed communication signal may be equivalent to an amplitude and/or phase of a second received spatially multiplexed communication signal. The amplitude of the first received spatially multiplexed communication signal is adjusted within the processing path used to process the first received spatially multiplexed communication signal.

Abstract: Aspects of a method and apparatus for user equipment (UE) channel acquisition in the presence of large frequency uncertainty in wideband code division multiple access (WCDMA) signals are provided. An efficient time-frequency domain search that may be utilized in cell communications may be performed by devising criteria that eliminates the unlikely frequencies hypotheses. An estimate for the frequency offset may be estimated in the remaining subset. For WCDMA applications, a UE may comprise a baseband processor that is enabled to detect a primary synchronization channel (P-SCH) code (PSC) for initial network synchronization. A portion of the baseband processor may generate a plurality of signal peak-to-noise-floor-average ratios associated with a plurality of test frequencies produced by a crystal oscillator. A highest of the signal peak-to-noise-floor-average ratios may be selected to determine the frequency offset of the crystal oscillator for use in power up operations.
