摘要: Colavolpe and Raheli have proposed (see Proc. IEEE Intern. Conf. Univ. Pers. Commun. (ICUPC'98), Florence, Italy, October 1998, Global Conf., (GLOBECOM'98), Sydney, Australia, 1998), noncoherent sequence detection schemes for any coded modulation. These produce hard decisions via a Viterbi algorithm. The current trend in digital transmission systems toward iterative decoding algorithms motivates an extension of these schemes. We propose soft-output algorithm linear modulations whose structure is similar to that the well-known by Bahl et al. (1974). application case combined differential or convolutional codes considered comparisons with are performed. As example processing, turbo considered.
