摘要

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，推导了精灵辅助系统误比特率的联合界。该联合界可用于解决误比特率（BER）很低时蒙特卡洛仿真难以获知系统错误性能的问题。仿真结果表明，在不同强度的湍流条件下，分组马尔可夫叠加传输系统在低误比特率区域的错误性能与精灵辅助下界贴合。精灵辅助等效系统的联合界与其仿真结果也贴合。在 BER=10

-5

时，记忆长度为 2 的分组马尔可夫叠加传输系统的性能与香农限的距离在1 dB以内。

Abstract

Based on the equivalent genie-aided system

the bit-error rate of the block Markov superposition transmission system was analyzed and the union bound of the bit-error rate of the genie-aided system was derived.When the bit-error rate was extremely low at which the Monte Carlo simulation was time-consuming

the union bound could be adopted to evaluate the performance of the block Markov superposition transmission system.Simulations under turbulence conditions from weak to strong are performed which show that

in the low bit-error rate region

performance of the block Markov superposition transmission system matches well with the lower bound.It is also illustrated that the derived union bound matches well with Monte Carlo simulation result.At the BER of 10

-5

block Markov superposition transmission system with transmission memory 2 performs within 1 dB away from the Shannon limit.
