Abstract:
1. A method for use in a receiver, the method comprising: determining a plurality of multiply result signals in a pre-multiplier portion of a multiple-mode correlator based at least in part on multiplying input sample signals x(n) with code chip signals c(n); selecting a first one of said plurality of multiply result signals for use by a first accumulator; and selecting a second one of said plurality of multiply result signals for use by a second accumulator, wherein said first and second accumulators are part of a plurality of accumulators of a correlation portion of said multiple-mode correlator, said plurality of accumulators being partitioned into a plurality of groups of accumulators based at least in part on a plurality of correlation modes, and wherein said plurality of groups of accumulators comprises at least two groups of accumulators, each of said plurality of correlation modes is operatively enabled to process at least four of said input sample signal x(n) per chip, each of said input sample signals x(n) is split into at least four sample phases, and each of said at least two groups of accumulators independently processes one of said at least four sample phases.
