fft1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图-fft1. Using Matlab generated sine wave, rectangular wave, as well as the white noise signal, and displa

根号升余弦匹配滤波器的仿真。用matlab仿真基带传输的最佳接收机，使用的脉冲的跟升余弦，信号是4pam。然后接收端进行匹配滤波之后采样量化恢复原信号。-Square root ascending cosine matched filter of the simulation

In this paper the analysis of the compression process was performed by comparing the compressed signal against the original signal. To do this the most powerful speech analysis and compression techniques such as Linear Predictive Coding (LPC) and Dis

几个MATLAB常用的小程序，适用于信号处理时用，平时也可用的，包括高斯噪声和平方根的求法。-Several commonly used MATLAB program, suitable for signal processing, and also can use at ordinary times, including gaussian noise, and the method to get the square root.
