Turbo product code decoding for concatenated space-time error correcting codes

International audienceThis paper presents iterative decoding structures for concatenated space-time error correcting codes (STECCs), based on the turbo product code decoding algorithm. Thanks to linear combinations of forward error correcting (FEC) codewords, established to create a space-time redundancy, a product code is reconstructed from concatenated STECC ensuring at the receiver an iterative turbo product code decoding scheme that outperforms the existing turbo-like receiver with an interference canceller optimized according to the minimum mean square error (MMSE) criterion
