码域发送参考脉冲超宽带系统性能

摘要

在时域和频域发送参考型脉冲超宽带通信系统的基础上,对码域发送参考脉冲超宽带通信系统的性能进行了研究,推导了基于脉冲峰值能量的系统误码率表达式,对该系统在加性高斯白噪声和多径衰落信道中的性能进行了仿真,并与时域和频域发送参考结构在抗多径十扰等多个方面进行了对比.理论分析和仿真结果表明,码域发送参考脉冲超宽带通信系统性能优于时域和频域系统.%Based on the time domain and frequency domain transmitted reference IR-UWB systems, this paper studies optimization design of code domain transmitted reference IR UWB system, and derives bit error rate (BER) of the system based on pulse peak energy. The system performance under the condition of additive Gauss white noise (AWGN) and multipath fading channel is simulated and compared with the time domain and frequency domain transmitted reference structures. Theoretical analysis and simulation results show that the performance of the code domain transmitted reference IR UWB system is superior to the time and frequency domain systems.
