Abstract:
A wireless system may receive a plurality of multipath signals from a plurality of transmitters and allocate per-cell modules for generating an interference suppressed signal from the multipath signals. Data symbols may be sequentially processed in the received multipath signals utilizing the per-cell modules and subtracting the processed symbols from a residual buffer storing the received multipath signals. Desired information received from one or more of the transmitters may be recovered utilizing the interference suppressed signal. Timing of the data symbols may be correlated utilizing a cell chip combiner. The data symbols may be descrambled utilizing conjugated scrambling codes associated with one of the plurality of transmitters. Orthogonal variable spreading factor (OVSF) codes may be generated utilizing a Walsh transform on the data symbols. Power levels of the OVSF codes may be estimated and estimated signals may be generated based on the OVSF codes and the estimated power levels.
