Research and Implementation of a Tamed Spread Spectrum System Based on Walsh Coding

Abstract

Spread spectrum communication is well-known by its excellent ability of anti-interference, anti-fading and good performance in confidentiality. The tamed spread spectrum communication system is developed on the basis of it. Most of the literature does not distinguish this spread spectrum technique from direct spread spectrum. In this paper, the performance of tamed spread spectrum with single -frequency interference is analyzed and simulated compared with direct spread spectrum. The conclusion is drawn that the tamed spread spectrum technology has a strong ability to resist random noise interference, but for human interference, its performance is seriously declined. The FPGA implementation method of tamed spread spectrum communication system is mainly studied as well.
