本文介绍信号处理和解释的双向流系统（BIPIS），在应用信号处理的基本理论对信号处理和信号解释之间建立双向流方面进行了初步探讨。这一系统的突出特点是信号处理过程随着对模糊和失真数据重分析的需要而动态地改变，即用信号处理的结果支持信号解释，而信号解释的结论反过来指导信号处理方法和控制参数的选择。该系统广泛适用于复杂环境下的信号处理，如变信噪比、多种可能信号源及两种或两种以上信号的同时发生而导致的隐藏或失真等情况。本文最后给出一个简单的实验台对系统流程加以直观地阐明。
This article introduces the BIPIS (signal processing and interpretation) system, and discusses the basic theory of signal processing to establish bidirectional flow between signal processing and signal interpretation. The salient feature of this system is that the signal processing process dynamically changes with the need to reanalyze fuzzy and distorted data, that is, the signal processing results support signal interpretation and the signal interpretation conclusion in turn directs the signal processing method and control parameters s Choice. The system is widely used in complex environment signal processing, such as variable signal to noise ratio, a variety of possible sources and the simultaneous occurrence of two or more signals caused by hidden or distorted situation. At the end of this paper, a simple test bench is given to illustrate the system flow intuitively.
