KALMAN FILTERING FOR SPACE-TIME CODED TRANSMISSIONS OVER FREQUENCY-SELECTIVE RAYLEIGH FADING CHANNELS

Abstract

The problem of multichannel estimation for space-time coded transmissions over frequency-selective Rayleigh fading channels is addressed. Under  fast fading conditions, receivers employing Kalman filtering and moderate complexity equalization schemes are proposed for both space-time block codes (STBCs) and space-time trellis  codes (STTCs). Simulation results of the proposed receivers demonstrate good performance.
