Blind maximum ratio combining and channel shortening for cyclic prefixed systems

Abstract

In this paper we propose a blind maximum ratio combining (MRC) technique along with an initialization method to improve the performance of the blind adaptive channel shortening algorithm called multicarrier equalization by restoration of redundancy (MERRY) in the 1times2 SIMO channel context. We show through analysis and simulations that the blind MRC technique allow us to take advantage of the spatial diversity improving considerably the performance of the MERRY algorithm in the SIMO context.
