摘要
提出了在强干扰(音干扰、其他用户干扰和高斯噪声)存在的情况下,直接序列扩频载波访问受限卫星中继器的模型。采用简化相量分析得到系统误码率的严格上限。比较了限制中继器系统的误码率和线性中继器系统的误码率。对于四相扩频码,在误差概率为10/sup -4/.>的情况下,由极限中继器引起的平均衰减的上界约为4 dB
Modeling multiple access to a hard limiting direct-sequence spread spectrum satellite repeater using phasor analysis
A model of direct-sequence spread-spectrum carriers accessing a limiting satellite repeater in the presence of strong interference (tone jamming, other users, and Gaussian noise) is presented. A simplified phasor analysis is used to obtain a strict upper bound on system bit error rate. Comparisons are made of the bit error rate for a limiting repeater system and that obtained for a linear repeater system. For a quadriphase spreading code, the upper bound on the average degradation due to the limiting repeater was approximately 4 dB for an error probability of 10/sup -4/.<>
