In order to meet the command of high efficiency and security in modern communication system,this paper gave a new parallel combinatory spread spectrum communication system based on the pulse modulation,which composited the advantages of the security and the high efficiency of pulse modulation UWB communication system and parallel combinatory spread spectrum communication system.And the new system could possess the high efficiency and fine security at the same time.The model of the new system was set up by the simulation software and then gave the simulation of the bit error rate(BER) performance of the system.With the results of the simulation,the new system was better than normal pulse modulation UWB communication system and normal parallel combinatory spread spectrum communication system of the BER performance.And the transmission rate of information could also be enhanced by changing the parameters of parallel combinatory spread spectrum.Simulation results verify fine BER performance,ability of information transmission and the feasibility of the system.
