Study on Bit Error Rate of Spread Spectrum Communication System based on MATLAB

Spread spectrum communication technology is a very important anti-interference communication technology,and thus becomes the hotspot of modern communication technology.For its bandwidth occupation is much lager than the minimum bandwidth required for the transmission of information,thus it could achieve the anti-interference goal.Compared with other communication systems,spread spectrum communication system has its unique advantage featuring in communication under negative signal-to-noise ratio.Different bit error rates influenced by various kinds of noise in the direct sequence spread spectrum communication system are analyzed and compared.Moreover,the relationship between the bit error rate and the signal-to-noise is studied and simulated with MATLAB under different kinds of noise.
