Hybrid Monte Carlo — Recursive identification algorithms for blind detection over a Rayleigh fading channel

Abstract

A joint detection and adaptive estimation scheme is presented for a Rayleigh fading channel. The channel is modeled as an autoregressive process and the communication system is modeled as a dynamic state space model. A new filtering method called hybrid Monte Carlo-recursive identification is used, which combines sampling based filters with classical recursive identification methods to estimate the transmitted symbol sequence and the channel fading.
