A new hidden Markov model for very bursty channels

In order to design good error control schemes for bursty channels, and also to facilitate performance analysis, it is important to develop accurate and simple statistical models for the channels of interest. In this work, we propose a new generative method to model the end-to-end profile of radio channels described by long well defined error bursts interleaved with long error free intervals. The proposed method, based on a simple hidden Markov model with a specific structure, achieves much better performance, with comparable complexity, than previous approaches proposed in the literature.
