Method and System for Low Complexity Conjugate Gradient Based Equalization in a Wireless System

A method for processing wireless signals, comprising:

• receiving first and second wireless signals comprising information transmitted from one or more transmit antennas;
• generating a correlation vector that corresponds to said first wireless signal correlated with a complex conjugate of said second wireless signal;
• and
• updating an equalizer tap according to said correlation vector upon determining that a signal-to-noise ratio (SNR) requirement is satisfied.

A system for processing wireless signals, comprising:

• one or more receive ports configured to receive first and second wireless signals comprising information transmitted from one or more transmit antennas;
• a correlator configured to generate a correlation vector that corresponds to said first wireless signal correlated with a complex conjugate of said second wireless signal;
• and
• a conjugate gradiant tap optimizer (CGTO) configured to update an equalizer tap according to said correlation vector upon determining that a signal-to-noise ratio (SNR) requirement is satisfied.
