Abstract
A Viterbi type algorithm is presented for adaptive estimation of MPSK sequences over a Rayleigh fading channel with unknown fading spectrum and unknown additive channel noise intensity. It uses a new, weighted least-squares decision metric. Simulations show significant performance gains over both differential detection and adaptive symbol-by-symbol detection proposed by Kam and Tay (see ibid., vol. 31, no. 13, p. 1022-3, 1994)
