NCO频率控制字的计算方法，可以应用在数字中频/基带等众多场景。(The calculation is NCO frequency control word ,which can be used in digital IF/baseband algorithms and many other scenes.)

Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.

MATLAB程序，用以实现2PSK数字信号的产生(MATLAB program to achieve generation of 2PSK digital signal)

脉冲编码调制（PCM）是数字通信的编码方式之一，在通信系统中完成将语音信号数字化的功能。PCM的实现主要包括三个步骤：抽样、量化、编码，分别完成时间上离散、幅度上离散及量化信号的二进制表示。(Pulse code modulation (PCM) is one of the encoding of digital communications, in a communication system will complete the function of digital speech signals. The realization of the PCM mainly includes three steps: sampling, quantization and coding, completed on the discrete time, the amplitude of discrete and quantify the binary representation of signals.)
