Abstract

To speedup the simulations aimed at different error control and interleaving schemes evaluation there is a need for generative models of the radio layer communication link. A method of modelling discrete channels with hard and soft decision outputs is suggested. This method is based on nested hidden Markov model (HMM) and implemented as COSSAP library modules. The verification made by simulations of GSM speech traffic confirmed the validity of suggested approach
