在语音识别系统中，端点检测的目的是要区分语音段和非语音段 ,它在自动语音识别中起着关键作用(In speech recognition systems, the purpose of endpoint detection is to distinguish between voice and non-voice segment, which in automatic speech recognition plays a key role)

ofdm系统的matlanb仿真，包含星座图，加窗，误码率等，希望对大家有帮助(ofdm system matlanb simulation, including the constellation, adding windows, error rate, we want to help)

对给定的系统实施基于内模原理的H无穷控制。并绘制阶跃响应图与bode图。同时加入了一定范围内的参数扰动，参数扰动时，系统同样可以稳定。(The implementation of H control based on the internal model principle of the given system. And draw the step response diagram and bode. At the same time, parameters are added to a certain range, and the system can be stable when the parameters are disturbed.)

直接序列扩频系统（DS，Direct Sequence）又称为直接序列调制系统或伪噪声系统（PN 系统），简称为直扩系统，是目前应用较为广泛的一种扩展频谱系统。要传送的信息经伪随机序列编码后对载波进行调制。在发信端越冬用扩频序列去扩展信号的频谱，在收信端，用相同的扩频友序列进行解扩，将展宽的频谱扩展信号还原成原始信号。因为伪随机序列的速率远大于要传送信息的速率，所以受调信号的频谱宽度将远大于要传送信息的频谱宽度，帮称之为扩频(Direct sequence spread spectrum (DS, Direct Sequence) modulation system, also known as direct sequence or pseudo-noise system (PN system), referred to as direct expansion systems, is currently the more widely used as a spread spectrum system. To send the information encoded by the pseudo-random sequence of carrier modulation. End of winter in the letter to extend the signal with the spreading sequence of spectrum, in the end prepared to receive and use the same sequence spread spectrum despreading friends, broadening the spectrum to restore the original signal expansion signals. Because the rate of pseudo-random sequence is much larger than the rate of information to be sent, so the frequency spectrum by adjusting the width of the spectrum is much larger than the width of the information to be sent to help is called spread spectrum)
