Patent ID: 7822108

Claim:
A Code Division Multiple Access (CDMA) receiver for sampling a received CDMA signal into a plurality of samples, the CDMA receiver comprising: a sampling control module, delaying the samples for a plurality of different delay lengths to obtain a plurality of series of delayed samples respectively corresponding to each of the delay lengths, and adjusting timings of a sampling trigger signal and a code generation trigger signal according to a sampling timing adjustment signal; a code generator, coupled to the sampling control module, generating a despreading code according to the code generation trigger signal; and a plurality of despreaders, coupled to the sampling control module and the code generator, decimating the plurality of series of delayed samples according to the sampling trigger signal to obtain a plurality of series of decimated delayed samples, and despreading the plurality of series of decimated delayed samples with the despreading code to obtain a plurality of output signals; wherein the sampling trigger signal triggers the despreaders to decimate the plurality of series of delayed samples at the same time to obtain the plurality of series of decimated delayed samples, and the despreaders demodulate the plurality of series of decimated delayed samples according to the same despreading code to obtain the plurality of output signals.
