LDRD 26573 Ultra-Low Power Spread Spectrum Receiver, FY02 Final Report
This report describes the development of an ultra-low power spread spectrum receiver based on a programmable surface acoustic wave (SAW) correlator. This work was funded under LDRD 02-26573, Ultra-Low Power Spread Spectrum Receiver. The approach taken in this project uses direct demodulation of a radio frequency (RF) signal from carrier frequency to data frequency. This approach was taken to reduce power consumption and size. The design is based on the technique of correlating the received RF signal with the preprogrammed spreading code. The system requirements, applications, design methodology, and testing results are all documented in the following pages.
