noisy communication channel是什么意思

用法例句

A low-complexity timing acquisition algorithm based on dirty template and least squares method for UWB systems is proposed in this paper.

本文给出了一种低复杂度的UWB同步捕获方法,该方法以有噪模板方法和最小二乘法为基础,采用两步法实现脉冲级同步捕获,克服了有噪模板方法在脉冲级捕获时性能不佳和最小二乘法复杂度高的缺点,仿真结果表明此改进算法在降低复杂度的同时能获得较好的同步捕获性能。
