The present invention generally relates to block code transmission receiver and method, and uses the maximum likelihood theory to generate correct block signal. The receiver of the present invention comprises a Feed-Forward Equalizer (FFE) for receiving block signal and converting the block signal into a first signal with minimum phase; an Inter-Symbol Interference (ISI) eliminator for receiving the first signal and a feedback signal that is used to eliminate the Inter-Symbol Interference of the first signal, the Inter-Symbol Interference (ISI) eliminator also generates a second signal not having Inter-Symbol Interference; a block detecting device for receiving the second signal and measuring the correlation between the second signal and each possible block, and for selecting the block code with the minimum distance as the best output block code; and a Feedback Equalizer (FBE) for receiving the block code output from the block detecting device and generating a feedback signal.
