AWGN信道中UWB-PAM的性能分析及仿真

Performance analysis and simulations of UWB-PAM in AWGN channel

超宽带 UWB传输技术以其低功耗、高速率、低检测率和低截获率等特点而在近年受到广泛重视 ,通过对 AWGN信道中利用 PAM完成 UWB端到端通信的误码率公式及其理论曲线分析 ,得出最佳非双极性 PAM脉冲信号的条件。推断出利用 UWB- PAM完成端到端通信的理论误码率趋向 。

UWB technology has attracted much attention in recent years because of its high data rate, low power consumption, low probability of detection and low probability of interception. This paper deduced the theory of BER for PAM end-to-end communications in AWGN, analyzed the BER curves, and drew the conclusions about optimal non-bipolar PAM signal. The paper predicts the tendency of UWB-PAM BER, and verifies the validity of both deduction and prediction through simulations.
