并行处理是高速实时信号处理领域研究的主要技术，随着信号处理技术的发展，并行处理技术越来越受到人们的重视。本文通过对数字信号进行多项式并行表示，提出了自适应有限冲激响应（ＦＩＲ）滤波器并行实现的几种新方法。作者对这些方法进行了性能分析和比较，狄得了一些有意义的结论。 Parallel processing is the main technology in the field of high-speed real-time signal processing. With the development of signal processing technology, parallel processing technology has drawn more and more attention. In this paper, a polynomial parallel representation of digital signals is proposed, and several new methods of parallel implementation of adaptive finite impulse response (FIR) filter are proposed. The authors conducted a performance analysis and comparison of these methods and made some meaningful conclusions.
