A full serial implementation of a M-level correlation based demodulator (100) includes a two's complement, pass-through, zero-out complex conjugate multiplier element (102), a boxcar filter (104) coupled to the multiplier element, a complex magnitude approximater element (106) coupled to the boxcar filter and a maximum value and index holding element (108). The multiplier element reuses common products along an M-level of cross-correlation to reduce multiplication functions at a rate 2 times M faster than a sampling rate at an input of the demodulator.
