Abstract :
We study channel estimation for V-BLAST MIMO-OFDM systems over multipath fading channels. A joint iterative channel estimation combining EM algorithm with turbo iterative decoding is presented. The simulation results showed that the performance of the systems became better as the number of iterations increased.
