Abstract

Over a power-limited additive white Gaussian noise channel (AWGN), the transmission performance can achieve the channel capacity when the input follows Gaussian distribution. Therefore, this paper found a promising ununiform-APSK (Amplitude Phase Shift Keying) constellation mapping "4+12F-APSK" which is optimized by the binary switching algorithm (BSA) using Harmonic mean after feedback to be the cost function, and presented a joint demodulation and decoding method based on high-performance code-modulation mapping to approach the channel capacity efficiently. In BICM-ID (Bit Interleaved Coded Modulation-Iterative Decoding), simulation results show that, in Rayleigh fading channel at BER (Bit Error Rate) of ten to the negative five, the proposed method outperforms the traditional rectangle 16QAM (Quadrature Amplitude Modulation) mapping as MESW (Maximum Squared Euclidean Weight), GRAY and SP (Set Partitioning) by 0.6dB at least; in AWGN channel at BER of ten to the negative three, this number is 0.3dB compared with MSEW and GRAY mapping. Moreover, both in Rayleigh and AWGN channels, the proposed method has 1dB~2dB performance gain compared with the other ununiform-16APSK mappings. It has a wide range of applications in resource limited networks such as mobile and broadcast communication.
