Abstract :
The problem of channel estimation and equalization is considered for the block interleaved transmission over diversity channels. Effects on channel estimation and equalization from the amount of training symbols, the depth of the interleavers and the size of data packets are investigated by evaluating the Cramer-Rao bound (CRB). The simulation results show that the block interleaved transmission may offer considerable gain in estimation and equalization performance
