Iterative channel estimation and decoding algorithm for quasi-coherent demodulation of Turbo coded GMSK signals

Tongxin xuebao, 2006
A new simple iterative channel estimation algorithm for quasi-coherent demodulation Turbo coded GMSK signals was presented. Based on the iterative decoding principle of Turbo code, the algorithm improved the channel esti- mation accuracy using output of ...
