ABSTRACT:
The spread spectrum receiver employs circuits based on direct conversion techniques. These circuits enable realization of spread spectrum receivers of greatly reduced complexity and of much higher chip rates that can be implemented with the standard approach of a fully digital receiver. With these circuits, the digital processing is performed at the data symbol rate and not at a multiple of the chip rate that is customary in state-of-the art spread spectrum and CDMA receiver design.
