摘要

摘要: 从脉冲超宽带(PPM-UWB)信号解调的角度, 该文探讨了PPM-UWB带通欠采样信号处理的信号重建算法, 并将零化滤波算法和ESPRIT算法进行了仿真对比。ESPRIT算法与零化滤波算法相比需要的最小带宽要求较大, 但是在同等带宽条件下, ESPRIT算法具有更好的抗噪声性能。

Abstract: The signal reconstruction algorithm with sub-Nyquist bandpass sampling in Pulse Position Modulation-Ultra Wide Band (PPM-UWB) signal processing is analyzed based on PPM-UWB signal demodulation. Then, the reconstruction method based on the annihilating filter and the Estimation of Signal Parameter via Rotational Invariance Techniques (ESPRIT) algorithm are compared using simulations. The total least squares ESPRIT algorithm, which requires high bandwidth, has better anti-noise performance than the reconstruction method based on the annihilating filter.
