Analysis of Pseudo-Noise Spread-Spectrum Communication over Randomly Time-Variant Channels Without Assuming Perfect Synchronization
The effect of certain time-variant channels on the performance of a PN spread-spectrum system is analyzed without assuming perfect synchronization of the receiver's PN sequence. The results show that maximizing the power of the despread signal can be markedly suboptimal concerning the signal-to-noise ratio and that even well-known tracking loops may exhibit only moderate performance.
