Abstract

A Multi-Code (MC) Code Division Multiple Access (CDMA) receiver receives N (where N>1) encoded signal channels over multiple air signal paths. In the MC-CDMA receiver, once a timing correlator means has recovered the timing and control signals for the data signal received over any particular signal path, those timing and control signals are utilized by each of the N data (second type) correlator means for decoding and despreading an associated one of the N data signal channels received over that path.
