ABSTRACT:
A CDMA receiver is provided which is operable to receive a CDMA encoded signal and decode the information therein utilizing a selected code. The systems utilizes a plurality of multiply-accumulation blocks (40) which are operable to receive the signal and compare the received signal with a Walsh-Hadamard code. The comparison and the accumulation is made only in the middle of a chip clock with the edges thereof blanked. This information in the middle of the chip clock is accumulated in an accumulator, the MAC (40), for a symbol period. This is then compared with a look up table and then a decision made as to the logic value thereof.
