Abstract :
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.
