A demodulator includes one or more modules operable to receive an input signal comprising symbols. A module receives a main signal comprising at least a portion of the input signal and splits the main signal to yield a branching signal and a remaining main signal. The branching signal travels along a first path, and the remaining main signal travels along a second path. The second path introduces a delay with respect to the first path. If there is a next module, the module sends a first portion of the remaining main signal to a next module as a main signal for the next module. The module combines the branching signal and at least a second portion of the remaining main signal to generate interference. The interference indicates a phase shift between a phase corresponding to a symbol and a successive phase corresponding to a successive symbol.
