Quantized CMA Equalization for Shaped Signal Constellations

IEEE Signal Processing Letters, 2004
Constellation shaping introduced to maximize channel capacity is detrimental to the performance of many cost function-based blind equalization algorithms including the constant modulus algorithm (CMA). We propose a new multimodulus algorithm closely related to CMA, but robust against changes in the statistical nature of the signal due to constellation ...

Shape codes in a 3D signal constellation

Proceedings of ICUPC - 5th International Conference on Universal Personal Communications, 2002
Shape coded modulation is a novel combined modulation and error-control coding technique. The basic algorithm is to map binary information digits onto pre-defined shapes within a given signal constellation, and to make use of these shapes to provide an error-control capability. Simulation results are presented for shape codes within a three dimensional

Combining BICM with trellis based constellation shaping

Proceedings of the 2009 International Conference on Wireless Communications and Mobile Computing: Connecting the World Wirelessly, 2009
In a bandwidth limited channel the constellation shaping can easily provide 1 dB SNR improvement. The conventional view is to handle coding and shaping as two separate operations. Because of that, it is usually difficult to incorporate shaping into decoder structure.
