Patent ID: 7277515

Claim:
A receiver for block code transmission, which comprising: a Feed-Forward Equalizer (FFE) receiving block signal and converting the block signal into a first signal with minimum phase; an Inter-Symbol Interference (ISI) eliminator receiving the first signal and a feedback signal and the feedback signal is used to eliminate the Inter-Symbol Interference of the first signal, and the Inter-Symbol Interference (ISI) eliminator also generates a second signal not having Inter-Symbol Interference; a block detecting device receiving the second signal and measuring the distance between the second signal and each possible block, and selecting the block code with the minimum distance as the best output block code, the block detecting device comprising: a Serial to Parallel Converter (SPC) converting the second signal to a parallel signal; a matrix multiplication device performing matrix multiplication for whole channel response and the parallel signal converted from the serial signal; a block correlation calculation device calculating the correlation between the signal output from the matrix multiplication device and each possible block; and a block selecting device selecting the block with the minimum distance as the best block; a channel matched filter placed between the Inter-Symbol Interference (ISI) eliminator and the block detecting device to increase S/N ratio; and a Feedback Equalizer (FBE) receiving the block code output from the block detecting device and generating the feedback signal.
