摘要

本文研究了正交部分响应直接序列扩频(QPR/DS)信号通过陆地移动卫星信道传输时的性能评估。信道表现出衰落和阴影以及加性高斯白噪声。衰落和阴影导致接收信号的包络和相位变化。本文推导了这两种变化引起的误差概率的上界，并对QPR调制的扩频和窄带陆地移动卫星通信信道进行了数值计算。推导出的表达式可用于陆地移动卫星数据通信系统的设计。

Quadrature partial response direct-sequence spread spectrum for land mobile satellite communication channel

The paper is concerned with evaluating the performance of a quadrature partial response direct sequence spread spectrum (QPR/DS) signaling when transmitted through a land mobile satellite channel. The channel exhibits fading and shadowing as well as additive white Gaussian noise. Fading and shadowing cause both envelope and phase variations of the received signal. The paper derives upper bounds of the probability of error due to both of these variations, numerical results are obtained for both spread-spectrum and narrow-band land-mobile satellite communication channel with QPR modulation. The derived expressions are useful for the design of land mobile satellite data communication systems.
