摘要：A continuous phase modulation method comprises the following steps:receiving a sequence of digital data symbols a(n) to be emitted; transforming thesequence of symbols a(n) to be emitted into a transformed sequence of symbols b(n),each symbol b(n) of which is equal to the sum of a symbol a(n) to be emitted and of acorrective factor equal to a transformation Tf applied to a plurality of differences (a(n)-a(n−1)) between two consecutive symbols to be emitted, the transformation Tf appliedbeing a combination c of at least two differences between two consecutive symbols ofthe sequence to be emitted, transformed by the application of a non-linear function f;filtering the sequence of transformed symbols b(n) with a shaping filter and modulatingthe filtered sequence with a phase modulator; said transformation Tf being defined so asto minimize interference between modulated symbols filtered by a receiving filter.
