WebbIn slow fading channels, the coherence time of the channel is long and encoding can be performed only over a single or a few fading states (e.g., time diversity). While encoding still averages out the randomness of the noise, it may not be possible to fully average out the randomness of the channel. WebbIn this paper, we have implemented two different OFDM channel estimation methods for single carrier systems in which one estimation method is based on fast fading channel or Rician channel and another method is based on the …
