A time-domain weighted linear successive interference cancellation detector for rapidly time-varying OFDMA communication systems ?
A low computational complexity weighted linear SIC detector is proposed. It can converge to either the decorrelator or the LMMSE detector for two distinct values. A reduced complexity version of the weighted linear SIC detector is also proposed. The proposed scheme is convergent if the weighting factor is between 0 and 1.
