摘要

本文研究了非线性放大对空时编码系统性能的影响。研究了在线性和非线性MIMO信道上采用16-QAM信号的16态空时码的成对错误概率(PWEP)和误码概率(BEP)性能。然后评估由于传输编码符号的非线性放大而导致的性能下降。结果表明，随着MIMO尺寸的增加，性能下降幅度增大。

Performance of space time codes over nonlinear MIMO channels

This paper investigates the effects of Non-linear amplifications on the performance of space-time coding systems. Pairwise Error Probability (PWEP) and Bit Error Probability (BEP) performance of 16-states space-time codes employing 16-QAM signals over linear and nonlinear MIMO channels are presented. Performance degradation due to non-linear amplifications of the transmitted coded symbols are then evaluated. The results show that the performance degradation increase with increasing MIMO dimensions.
