摘　　要：为了改进超宽带通信系统的性能,通过对平衡Gold码的介绍与分析,提出了一种将平衡Gold码用于超宽带的多址接入技术,并对脉位调制(PPM)和脉幅调制(PAM)的超宽带系统进行Matlab仿真。仿真结果表明:该方法产生的跳时序列比传统跳时码序列具有更低的误码率。Ultra-wide band is particularly promising for short-distance wireless communication field.The multiple access of UWB is the key technology.The design of time-hopping sequences is very important in UWB communication system.In this paper,a multiple access method using balance Gold code for time-hopping sequence was presented for improving the performance of system.And pulse position modulation（PPM） and pulse amplitude modulation（PAM） were simulated on the platform of Matlab.Through computer simulation,high system capacity of the proposed system and superior performance over the conventional TH-based UWt5 systems in the channel of AWGN were verified.
