The Turbo equalization in Bit Interleaved Coded Modulation with Iterative Decoding
Conventional receivers execute equalization and channel decoding independently. Turbo equalization is a technique which links equalization with decoding. It gets better performance by exchanging the extrinsic information iteratively between the equalizer and decoder. We apply Turbo principle to the equalization in BICM-ID system and perform the Turbo equalization based on DFE (decision-feedback equalizer). Simulation results show that this algorithm leads to convergence in ISI channels with different fading degree and it approaches the performance in AWGN gradually along with the increasing SNR. Compared with the classical DFE algorithm, it has better performance.
