Abstract

Modulo lattice additive noise (MLAN) channels appear in the analysis of structured lattice codes with lattice decoding for Costa's dirty-paper channel and the additive white Gaussian noise (AWGN) channel. Building on the recent result on the optimal density of an infinite constellation over an AWGN channel, in this paper, it is shown that with a proper choice of the shaping lattice and the scaling parameter, the dispersion of the MLAN channel is asymptotically the same as that of the (zero-interference) AWGN channel at the same signal-to-noise ratio.

模晶格加性噪声信道的色散
在对Costa的脏纸信道和加性高斯白噪声信道进行格解码的结构格码分析中,出现了模格加性噪声信道(MLAN)。本文在最近关于AWGN信道上无限星座最优密度的研究结果的基础上,证明了在相同信噪比下,只要选择合适的整形晶格和标度参数,MLAN信道的色散与(零干扰)AWGN信道的色散是渐近相同的。
