Patent ID: 7650083

Claim:
A demodulator operable to demodulate a signal, comprising: two or more modules in a series arrangement operable to receive an input signal, the input signal comprising a plurality of symbols, a module of the two or more modules operable to: receive a main signal comprising at least a portion of the input signal; split the main signal to yield a branching signal and a remaining main signal, the branching signal traveling along a first path, the remaining main signal traveling along a second path, the second path introducing a delay with respect to the first path; send a first portion of the remaining main signal to a next module as a main signal for the next module, if there is a next module; and combine the branching signal and at least a second portion of the remaining main signal to generate interference, the interference indicating a phase shift between a phase corresponding to a symbol of the plurality of symbols and a successive phase corresponding to a successive symbol of the plurality of symbols.
