Abstract:
Methods and systems for processing signals in a receiver are disclosed herein and may comprise receiving WCDMA signals via M receive antennas, tracking a plurality of received clusters within the received WCDMA signals, and estimating a complex phase and amplitude of a portion of each of the received clusters. A single cluster may comprise an aggregate of received WCDMA signal paths and (M-1) phase shifters may be utilized for the estimating of the complex phase. Complex waveforms, comprising in-phase (I) and quadrature (Q) components for the received clusters within the received WCDMA signals, may be processed. The processed complex waveforms comprising the in-phase and quadrature components may be filtered to a WCDMA baseband bandwidth. A phase and/or amplitude for at least one of the received WCDMA signals may be adjusted utilizing the estimated complex phase and amplitude. The phase and/or amplitude may be adjusted continuously and/or at discrete intervals.
