摘要： In wireless systems, method and system for weight determination in a single channel (SC) multiple-input multiple-output (MIMO) system for WCDMA/HSDPA are provided. Models of signals received in multiple receive antennas may be determined in a single weight baseband generator (SWBBG) from propagation channel estimates and noise statistics. The models may be utilized to determine combined signal and noise components. The combined signal and noise components may be utilized to determine a plurality of signal-to-noise ratio (SNR) or signal-to-interference-and-noise ratio (SINR) values for various phase and/or amplitude factors. The SINR may be utilized when either single or multiple interfering signals are present. A highest of the SINR or SNR values may be selected to determine a channel weight to apply to the additional receive antennas.
