Noncoherent adaptive channel identification algorithms for noncoherent sequence estimation

  title={Noncoherent adaptive channel identification algorithms for noncoherent sequence estimation},
  author={Robert Schober and Wolfgang H. Gerstacker},
  journal={IEEE Trans. Communications},
In this letter, two novel noncoherent adaptive algorithms for channel identi cation are introduced. The proposed noncoherent least{mean{square (NLMS) and noncoherent recursive least{squares (NRLS) algorithms can be combined easily with noncoherent sequence estimation (NSE) for M{ary di erential phase{shift keying (MDPSK) signals transmitted over intersymbol interference (ISI) channels. It is shown that the resulting adaptive noncoherent receivers are very robust against carrier phase variations… CONTINUE READING
