We show that to lower the sampling rate in a spread spectrum communication system using Direct Sequence Spread Spectrum (DSSS), compressive signal processing (CSP) may be applied to demodulate the received signal.
This may lead to a decrease in the power consumption or the manufacturing price of wireless receivers using spread spectrum technology.
We propose a novel, simplified measurement scheme for spread spectrum systems, that is simpler and cheaper to implement than other current state-of-the-art aquisition methods.
Our theoretical work is exemplified with a numerical experiment using the IEEE 802.15.4 standard’s 2.4 GHz band specification.
