研究了非高斯脉冲信道上的分组马尔可夫叠加传输机制。基于精灵辅助等效系统,分析了分组马尔可夫叠加传输系统的性能下界。仿真结果表明,在特征因子不同的非高斯脉冲信道上,分组马尔可夫叠加编码技术均可获得较高的编码增益,且误比特率较低区域的误码性能均可与精灵辅助下界贴合。在BER = 10
-5
时,分组马可夫叠加传输系统便可达到距离香农限约0.85 dB的性能。
Block Markov superposition transmission scheme was used over channels with symmetric alpha-stable (SαS) impulsive noise.Based on the equivalent genie-aided system
the lower bound of the block Markov superposition transmission system was analyzed.Numerical simulations over non-Gaussian impulsive channels with different characteristic exponents show that
in the low bit-error rate region
performance of the block Markov superposition
transmission system matches well with the lower bound.Block Markov superposition transmission scheme performs well (with 0.85 dB away from Shannon limits at the BER of 10
-5
) over non-Gaussian impulsive channels.
