摘　　要：在平流层通信优化研究中,由于空中存在较强的人为干扰和存在较大程度多径消耗,引起平流层通信效果差。当前的抗干扰模型是对非人为干扰为基础进行研究的,对人为干扰没有涉及。传统抗干扰模型对人为干扰的抗干扰效果差。提出一种平流层通信中抗部分带干扰优化方法。将平流层通信信道等效为Nakagami衰落信道,提出在上述信道下错误率性能识别的新方法,采用噪声归一化合并方法进行分析错误性能,利用了概率密度函数(pdf)和特征函数(CF)作为基础进行仿真,结果表明,提升了平流层通信系统抗干扰性能。In this paper, an optimization method for anti-partial-band interference in the stratosphere communi- cation was proposed. The channel in the stratosphere communication was made equivalent to Nakagami fading chan- nel. The new method of the error rate performance identification under the above mentioned channel was proposed. The noise normalization combining method was used to analyze error performance, and the probability density function （PDF） and characteristic function （CF） were taken as a basis for the simulation. Simulation results show that it can improve the anti-interference performance of stratosphere communication system.
