A constellation labeling map is the assignment of a bit pattern to each symbol in a signal-set constellation. In a system with bit-interleaved coded-modulation and iterative decod...
—The error floor of bit-interleaved coded modulation with iterative decoding (BICM-ID) can be minimized for a particular constellation by maximizing the harmonic mean of the squ...

Structurally distinct constellation labelings exist within both the Gray code and the set-partitioning paradigm. Different labeling choices within either paradigm can provide diffe...
Abstract−Several high performance LDPC codes have paritycheck matrices composed of permutation submatrices. We design a parallel-serial architecture to map the decoder of any str...
Motivated by a recent surge of interest in convex optimization techniques, convexity/concavity properties of error rates of the maximum likelihood detector operating in the AWGN ch...
