Abstract :
We describe a modulation/coding scheme combining M-FSK modulation with diversity and coding to make the transmission robust against permanent frequency disturbances and impulse noise. We use simple non-coherent detection. The scheme can be considered as a form of coded frequency hopping and is easy extendable. We give a generalized construction procedure for new trellis codes of various rates and constraint lengths using our previously published technique of distance preserving mapping. Maximum likelihood decoding of these codes can follow naturally
