Abstract

In this paper, we propose an efficient channel estimation technique for orthogonal frequency-division multiplexing (OFDM) systems with transmitter diversity. The proposed technique estimates uniquely all channel frequency responses needed in space-time coded OFDM systems using " comb-type " training symbols. The computational complexity of the proposed technique is reduced dramatically, compared with the previous minimum mean-squared error (MMSE) technique, due to the processing made all in tile frequecy-domain. Also, several other techniques fur mitigating random noise effect and tracking channel variation are discussed to further improve the performance of the proposed approach. Tile performances of tile proposed approach are demonstrated by computer simulation for mobile wireless channels.
