用matlab编写的除法计算器,能够实现除法运算(division calculator is written by matlab)

说明：  传统的脉搏血氧R值提取大多采用脉搏波的峰谷值法.一个脉搏周期的峰谷值往往不能反映真实的R值，因此通常采用多个周期峰谷值的平均来提高R值的精度。提供了移动平均算法进行脉搏血氧信号特征值提取源码。(Traditional pulse oximetry R value extraction most of the peak value of the pulse wave method. A peak value of pulse cycles often do not reflect the true R value, usually more than one cycle, the average of the peak value to improve the accuracy of the R value. Moving average algorithm to extract the source pulse oximeter signal eigenvalue.)

说明：   R/S分析法程序,用于分析时间序列波形特征(R/S analysis program for analyzing the time series waveform feature)

利用谱减算法实现对航空录音的处理。主要思想是相对语音进行加噪声，然后再利用算法去噪声，比较前后信噪比的变化。根据实验结构，去噪效果明显。(The use of spectral subtraction algorithm for handling aviation record. The main idea is to increase the relative voice to the noise, and then use the algorithm to noise, signal to noise ratio before and after the change. According to the experimental structure, de-noising effect is obvious.)

此程序为书上源码，功能是描述16QAM载波调制信号在AWGM信道下的性能，有误码率分析图(This program is a source book, the function is to describe the 16QAM modulation signal performance at AWGM channel has BER analysis chart)
