The invention relates to a method of non-coherent decoding an encoded CPM signal received by a wireless receiver and a CPM decoder implementing the method wherein the signal is generated by a transmitter using a serial concatenation of an outer encoder an interleaver and an M-ary CPM modulator and may have a frequency-hopping RF carrier. In a preferred embodiment the method includes iteratively decoding the received signal by first recursively fording a sub-set of dominant sequences of CPM symbols that maximize a path metric for one hop interval using a non-coherent CPM detector determining on the basis of this sub-set a sequence of soft inner bits decoding these soft inner bits with an …
