Modified continuous phase modulation communications system and related methods

A communications device operable for communicating with another communications device comprising a receiver and a single pulse-matched filter linear demodulator cooperating therewith, the 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.

A communications method comprising:

• modulating by a first communications device a coded waveform using a constant phase modulation (CPM) to generate a non-linear CPM waveform;
• generating, at the first communications device, a linear representation of the non-linear CPM waveform comprising a plurality of pulses;
• removing 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
• transmitting the modified linear representation of the non-linear CPM waveform;
• and
• demodulating the modified linear representation of the non-linear CPM waveform transmitted from the first communications device in a second communications device comprising a single pulse filter linear demodulator.
