Tracking time-selective fading channels for space-time block coding in impulsive noise

This paper addresses the problem of estimation and tracking of non-Gaussian channels for space-time block coding. Based on the coding/decoding technique, we propose a robust Interacting Multiple Model (IMM) estimator approach in estimating time-selective fading channels when the measurements are perturbed by the presence of impulsive noise. The impulsive noise is modeled by a two-term Gaussian mixture distribution. The IMM estimator is a very …
