摘要
文章首先介绍了跳时超宽带(TH-UWB)信号,推导了在加性高斯白噪声(AWGN)信道条件和多径条件(MP)下,基于重叠和正交脉冲信号的系统误码率公式,并给出了仿真结果。仿真结果表明,在AWGN信道条件下,基于重叠脉冲信号的跳时二进制脉位调制(TH-BPPM)系统的性能优于基于正交脉冲信号的系统。多径条件下的正交TH-BPPM系统的性能优于AWGN信道条件下的系统性能。
In this paper, the TH-PPM UWB signal is introduced and the BER formula of the overlapped and orthogonal signalbased system under the AWGN channel and multi-path conditions derived. The simulation results show that under the AWGN channel condition, the overlapped pulse signal-based TH-BPPM system has better performances than the orthogonal pulse signal-based system, while the orthogonal TH-BPPM system performance under the multi-path condition is superior to that under the AWGN channel condition.
