Abstract :
This work studies the performance of Bit Interleaved Coded Modulation with a single decision feedback. The separation of demodulation and decoding in BICM inevitably reduces the channelpsilas capacity. Altering the conventional bit-mapping in BICM and allowing a single decision feedback greatly reduces the capacity loss. The extra complexity due to the single decision feedback appears well justified for dense constellations.
