METHOD AND DEVICE FOR MULTI-USER DETECTION WITH SIMPLIFIED DE-CORRELATION IN A CDMA SYSTEM

摘要

A simplified de-correlation method in CDMA multi-user detection comprises: a. receive wireless symbols S; b. obtain a channel correlation matrix R, take a part from R to get a partial correlation matrix R_P; c. do inversion operation to the partial correlation matrix R_P, then obtain matrix V^(m); d. recover original data symbols D from received symbols S by V^(m) that the location of original data symbols D corresponds to.
