Abstract

In this paper, we propose a novel decorrelation receiver for multiple-input multiple-output (MIMO) block fading channels. The proposed design breaks the correlation between soft-decision-directed channel estimation (SCE) and data detection, and thus improves the performance of existing receivers that do not take such correlation into account. Computer simulations confirm that the decorrelation receiver yields excellent performance when applied to the Markov Chain Monte Carlo (MCMC) MIMO detector and the soft minimum mean-square-error (MMSE) MIMO detector.
