摘要
针对极化干扰对星地数据传输系统的影响,归纳影响极化干扰的主要因素,推导星地数据传输系统极化干扰的理论模型,仿真数据传输系统在不同的调制体制和信道编码方式下的误码率恶化情况,比较在相同程度的极化干扰下各体制传输性能试验结果,分析在不同的Eb/N0工作门限下,星地遥感数据传输系统所受极化干扰影响的规律。
For the effect of polarization interference on satellite-to-grou nd data transmission system,the major factors that affect polarization interfer ence are concluded,the theoretical model of polarization interference is derive d,the deteriorations of bit error rate（BER） of different modulation systems an d channel coding modes are simulated,the transmission performance test results of each system in the same degree of polarization interference are compared,and the rules that satellite-to-ground remote sensing data transmission system are affected by polarization interference in different Eb/N0 wor king thresholds are analyzed.
