Abstract-- In multi-antenna system, the correlations between
the receiver antennas degrades the systems performance. In this
paper, we propose a spatial decorrelation receiving technique in
frequency-selective SIMO channels. A spatial-to-modal matrix is
placed after the SIMO channel output to remove the correlations
between the receiver antennas caused by the limited antenna
separations. Simulation results of this newly proposed spatial
decorrelation design demonstrate favourable BER improvement
and better system performance.
I. INTRODUCTION
Multi-antenna communication systems have drawn increase
attention due to the higher capacity and promising improved
performance. For frequency-selective fading channels, which
