Patent ID: 8711956

Claim:
A communications system comprising: a first communications device comprising a transmitter and a modulator cooperating therewith and configured to modulate a coded waveform using a constant phase modulation (CPM) to generate a non-linear CPM waveform, generate a linear representation of the non-linear CPM waveform, the linear representation comprising a plurality of pulses, remove all but a first pulse adjacent a first end of the plurality of pulses and a second pulse adjacent a second end of the plurality of pulses to define a modified linear representation of the non-linear CPM waveform, the first and second pulses having at least one pulse therebetween, and transmit the modified linear representation of the non-linear CPM waveform; and a second communications device comprising a receiver and a single pulse-matched filter linear demodulator cooperating therewith and configured to demodulate the modified linear representation of the non-linear CPM waveform transmitted from said first communications device.
