WebIn MISO mode the same exper- iments were repeated using a Ricean channel (Guerra, 2012) and the obtained results were comparable with results obtained with the Rayleigh channel. On the other hand, the second scenario which was very similar to the first one the SISO mode was tested using two AWGN channel models and it fails. WebWe also show that BICM-ID designed for fading channels usually has a very good performance over the additive white Gaussian noise (AWGN) channel while the …
