The increasing demand of achieving high data rates in modern communication systems requires highly efficient bandwidth utilization. For this purpose, multilevel modulation schemes are used in association with forward error correction (FEC) codes in order to approach the channel capacity. However, there is a gap between the capacity of a uniform signal… (More)

Bit interleaved coded modulation with iterative demapping and decoding (BICM-ID) is an effective technique to achieve high spectral efficiency with performance close to capacity limits. However, the use of non-uniform signal constellation following a Gaussian distribution instead of conventional equiprobable signaling provides a further improvement, i.e.… (More)
