THE DESIGN AND IMPLEMENTATION OF DECIMATOR BASED ON FPGA ABSTRACT Software radio is regarded as the developing direction of communication in future, and as one part of this, decimator change the high rate dataflow to a lower one, which meets the require of real-time processing and makes software radio come true.

软件无线电是未来通信的发展方向，而作为其重要组成部分之一的抽取器，将难以实时处理的高速数据流变为低速率信号，使软件无线电的实现成为可能。

As a result of half registers requirement, the 24.6% area reduction for high order (126th-order) FIR filter is obtained, which result in 15.8% area reduction for the 4-stages decimator (20.9% area reduction for 3-stages decimator).
