摘要：
In this paper we present a method to build discrete channel (DC) models that speed up simulations and facilitates analysis of error control strategies. This method is based on nested hidden Markov models (HMM) and takes into account soft decision outputs. The verification of DC model made by simulations of wide-band DS-CDMA (WCDMA) traffics confirmed the validity of suggested approach. Realistic DC models based on nested HMM are built for different coding and interleaving schemes evaluation. At the same time these models provide a basis for different FEC-ARQ schemes studies.
