A new design of pulse waveform for waveform division multiple access UWB wireless communication system

Abstract

Waveform Division Multiple Access (WDMA) based on the orthogonal wavelet function is recently presented due to its admirable characteristics. However, the communication performance of the existing waveform of the system breaks down drastically as the number of users increases. In order to meet the communication requirement for WDMA-UWB system with massive users, a new design of pulse waveform is proposed in this paper. The correlation property and Bit Error Rate (BER) performance is raised apparently and close to that of the single-user system.
