Abstract:
1. In a communication system comprising a transmitter and a receiver, wherein the transmitter comprises an outer encoder followed by a transmitter interleaver and an M c -ary continuous phase modulation (CPM) modulator for transmitting a CPM signal modulated with a sequence of M c -ary symbols, a method for non-coherent decoding of the CPM signal received by the receiver via a communication channel, the method comprising: a) identifying CPM symbol positions in the received CPM signal; b) selecting a portion of the received CPM signal comprising N consecutive CPM symbol positions; c) generating a sequence of N d) providing the sequence of N e) generating a sequence of N f) interleaving the sequence of N g) iteratively repeating the sequence of steps (c)-(f); and, h) generating a decoded sequence of N
