For Turbo coded V-BLAST MIMO-OFDM systems,a joint iterative decision feedback channel estimation and detection scheme were presented,which combined the Turbo iterative decoding with least square channel estimation,and made full use of the soft systematic bits and soft parity bits of Turbo iterative decoding to improve the channel estimation performance.

Turbo codes, with a PCCC coding architecture and a SISO&iteration decoding strategy, is a new class of error correction codes whose performances are close to Shannon s limit under computer simulation.

Turbo codes, with a PCCC coding architecture and a SISO & iteration decoding strategy, are a very powerful error correction codes that bring the performance of practi.
