Abstract :
Despite the widespread use of forward-error coding (FEC), most MIMO blind channel estimation techniques ignore its presence, and instead make the simplifying assumption that the transmitted symbols are uncoded. However, FEC induces code structure in the transmitted sequence that can be exploited to improve blind multiple input multiple output (MIMO) channel estimates. In this work we exploit the iterative channel estimation and decoding performance for blind MIMO equalization. Experiments show the attractive improvements by exploiting the existence of coding structures.
