匹配滤波器在现代通信系统中不可缺少,它的性能的好坏在很大程度上决定系统的性能。FPGA的发展为通信系统的设计提供了十分方便的硬件环境。文中提出了一种匹配滤波器在FPGA中优化实现的方法,它能在不影响系统性能的条件下大大减少对资源的消耗率。 Matched filters indispensable in modern communication systems, its performance is good or bad to a large extent determine the performance of the system. The development of FPGA provides a very convenient hardware environment for the design of communication system. In this paper, we propose a method to optimize the matched filter in FPGA, which can greatly reduce the resource consumption rate without affecting system performance.
