DECISION-DIRECTED NLMS EQUALIZER BY DESPREADING WITH A PARENT CODE OF A GROUP OF ACTIVE CODES.

摘要

A method for equalization in a code-division multiple access radio receiver adapts a pilot-aided equalizer more than once every primary common pilot channel (PCPICH) period for tracking fast time -varying channels. It then uses partial-despreading over a PCPICH period with a parent code to obtain a plurality of consecutive y- filter outputs during each PCPICH period, wherein an interference subspace region may also include active codes.
