Abstract
In this paper, a hybrid DS/TH multiple access scheme is proposed for UWB impulse radio system on the basis of TH-PPM theoretical research. This scheme makes use of time hopping for multiple access and BPSK for data modulation. It utilizes the characteristics of PN sequence signal of DS to suppress further the multi-user interference of TH-PPM system. Results of performance analysis show that DS/TH scheme has higher system capacity than TH-PPM scheme.
