| 摘 要： | 研究了基于单比特采样接收的IR—UWB系统中采样抖动对性能的影响。论文给出了采样抖动的简化分析模型，推导了AWGN信道下全精度采样系统和单比特采样系统的误码率理论解。论文通过仿真实验验证了理论分析的正确性，并分析比较了全精度采样系统、单比特采样系统在AWCN信道与多径衰落信道下的抗采样抖动性能及其原因。

| Abstract: | This paper investigates the effect of sampling timing jitter in IR-UWB system based on monobit sampling.To address this problem,we develop a simplified model of sampling jitter and derive generic bit error rate expressions for both monobit receiver and full-resolution receiver with sampling jitter in AWGN channel,and validate them with simulation results.Then,we compare and explain the difference of sampling jitter's effect between monobit and full-resolution receiver in AWGN channel and multipath fading ch... |
