Abstract
A Multi-Code (MC) Code Division Multiple Access (CDMA) receiver receives N (where N.gtoreq.1) encoded signal channels over multiple air signal paths. The N signal channels are encoded using a properly chosen subset of Walsh codes based on a Walsh-Matrix, W.sup.M, where M is a power of two. In the disclosed MC-CDMA receiver, a timing correlator means recovers the timing and control signal for the N signal channels received over any particular signal path; a FWHT circuit together with a second correlator means decodes all of the N signal channels.
