Abstract

In order to improve information transmission rate in unit bandwidth, using direct-sequence spread-spectrum CDMA thinking, creatively present a new multi-path direct sequence spread spectrum wireless communication systems´ model, and give its multi-path interference performance based on MATLAB. Simulation results show that the system can increase the information transmission rate in unit bandwidth through enhancing the length of the spreading code and the SNR.
