Abstract :
In this paper, we propose an algorithm for the design of space-time equalizer in asynchronous MIMO-OFDM systems. The equalizer is designed to the co-channel interference and combat asynchronism as well as minimize a lower bound to the symbol error rate. Numerical simulations show good uncoded bit error rate performance for our proposed algorithm.
