摘　　要：在水下通信的自适应门限信号检测过程中,采用一个固定的阈值进行判决,这种方法忽略了信号和噪声之间的动态关系,误码率较高。基于此,研究水下通信中的自适应门限信号智能检测方法。首先识别信号的特性,对信号进行初步分类。其次根据识别的信号特性,动态调整门限值,以确保在不同的信号环境下都能获得最佳的检测效果。最后利用调整后的门限值判决接收到的信号,区分出有效信号、噪声或无效信号,从而智能检测水下通信信号。实验结果证明了该方法在不同信噪比条件下的卓越性能和可靠性,为水下通信系统的性能提升提供了重要依据。In the process of adaptive threshold signal detection in underwater communication,a fixed threshold is used for decision-making,which ignores the dynamic relationship between the signal and noise and has a high bit error rate.Based on this,research on intelligent detection methods for adaptive threshold signals in underwater communication.Firstly,identify the characteristics of the signal and preliminarily classify it.Secondly,according to the recognized signal characteristics,the threshold value is dynamically adjusted to ensure the best detection effect in different signal environments.Finally,the adjusted threshold value is used to make a decision on the received signal,distinguishing between valid signals,noise,or invalid signals,thereby achieving intelligent detection of underwater communication signals.The experimental results have demonstrated the excellent performance and reliability of this method under different signal-to-noise ratio conditions,providing important basis for improving the performance of underwater communication systems.
