1. An N-phase multi-amplitude modulation receiver, comprising: a signal coupler block coupled to a down conversion mixer array block that includes N phases including N mixer elements which receive a first input signal from said signal coupler block and a second input from a local oscillator (LO) circuit that provides N overlapping phase signals coupled as said second input to respective ones of said N mixer elements; wherein outputs of said N mixer elements are coupled to a baseband filter (BBF) block that has outputs coupled to inputs of a decision threshold block including decision threshold elements each including a signal input and comprising at least one comparator that is coupled to receive at least one voltage threshold (V TH ) value; a phase ordering and mapper block coupled to said N mixer elements that selects M out of said N phases by enabling M out of said N mixer elements; a digital logic and control block coupled to control a filter gain and corner frequency of said BBF block and control said V TH value for said decision threshold block, said decision threshold block for comparing a signal received to said V TH value, wherein outputs from said decision threshold block are coupled to inputs of a M-input decision combiner which provides a single data output.
