Abstract  Abstract

A plurality of code division multiple access (CDMA) channel signals are received as a received signal. The received signal is despread using a code of a first channel of the plurality of CDMA channel signals to produce estimates of the first channel. The estimates of the first channel are respread using the code of the first channel. The respread estimates of the first channel are subtracted from the received signal to produce a subtracted signal. The subtracted signal is despread using a code of a second channel of the plurality of CDMA channel signals to produce estimates of the second channel.
