Abstract :
An iterative channel estimation based on maximum likelihood (ML) algorithm for multiple input multiple output orthogonal frequency division multiplexing (MIMO OFDM) systems is proposed in this paper. From simulation results, the iterative channel estimation algorithm can provide better mean-square-error and bit error rate performance than conventional methods.
