Method and apparatus for generating combination output for acquisition by coherently combining correlation outputs of multiple channels

Abstract

A multi-hypothesis combination circuit includes a coherent combination circuit and a selection circuit. The coherent combination circuit generates a plurality of coherent combination outputs by performing coherent combination according to a plurality of correlation outputs and a plurality of sign sequences, wherein the plurality of correlation outputs correspond to a plurality of channels, respectively, and each of the plurality of coherent combination outputs is derived from the plurality of correlation outputs and one of the plurality of sign sequences. The selection circuit generates and outputs a combination output of the multi-hypothesis combination circuit according to the plurality of coherent combination outputs.
