AntiNoise Performance Analysis of Spread Spectrum System
Mingji Yang, Aili Wang · 2012
The anti-noise performance of direct sequence spread spectrum (DSSS) communication system is analyzed in this paper. The new result given in the paper shows that anti-noise performance of DSSS system is different from classic result. The attenuation to input narrowband noise in DSSS system is the function of the relative position between the narrowband noise and carrier frequency of DSSS system, and it is discontinuous. The attenuation to input broadband noise is about 0.46dB better than in classic result. The results can be utilized in design and application of spread spectrum system.
