perona-malik算法,包括算法和测试(perona-malik)

低频信号先进行放大，再调制解调，设计发射机和接收机(Low-frequency signal is first amplified, and then modulation and demodulation, the transmitter and receiver design)

MATLAB学习资料，感兴趣的朋友可以下载(err)

说明：  用于生成不同频段的扫频信号，以供后期开发使用(create swept-frequency signal indifferent frequency channel )

The funcstion subroutine festotf.m converts a state space form of system into a transfer function form.

语音识别技术的最终目标是要让计算机能与人自由交谈。目前，连续语音识别技术正趋于成熟，语音识别也延伸出了诸多实用化的研究方向。今后，语音识别的重点将集中在自然话语识别与理解、实时语音识别和语音识别鲁棒性等方面。作为一门交叉学科，语音识别所涉及到的技术有信号处理、模式识别、概率论和信息论、发声机理、听觉机理和人工智能等。(The ultimate goal of speech recognition technology is to make computers and allowing others to speak freely. At present, continuous speech recognition technology is maturing, voice recognition is also extended out a lot of practical research directions. In the future, speech recognition will focus on Spontaneous Speech Recognition and Understanding, real-time speech recognition and speech recognition robustness and so on. As an interdisciplinary subject, speech recognition technology involved in a signal processing, pattern recognition, probability theory and information theory, vocal mechanism, hearing mechanism and artificial intelligence.)

该模型主要实现Chirp系统中Chirp信号的BOK调制，Chirp信号分为上扫频和下扫频信号，可以通过对正余弦信号进行BOK调制来产生。(This model mainly realize the BOK modulation Chirp Chirp signal in the system, under the Chirp signal is divided into the upper frequency sweep and frequency sweep signal, can pass to BOK is cosine signal modulation to produce. )
