16QAM信号调制解调Matlab仿真程序(16QAM signal modulation and demodulation Matlab simulation program)

该程序（基于matlab）为小波变换在数据压缩方面的应用。原理：数据可分为高频部分和低频部分，高频部分反映了细节，而低频部分则反映概貌，故压缩部分应为高频部分。数据经此程序变换后将压缩为原来的一半。(This program (based on matlab) for the wavelet transform applications in data compression. Principle: Data can be divided into high-frequency part and low frequency, high frequency part of the reflection of the details, partly reflecting the profile of low frequency, it should be for the high frequency part of the compression part. Data will be compressed by this program change to the original half.)

是一个四发四收的球型译码程序，编码是卷积码，调制方式是BPSK，用Vblast来实现解码。(Is a collection of four four-ball type decoding procedures, coding is a convolutional code, modulation is BPSK, used to achieve the decoding Vblast.)

扩展卡尔曼滤波算法的matlab程序，（字数不够，增加字数的）(Extended Kalman filter algorithm matlab program)

说明：  msk调制解调程序，利用matlab进行仿真，通信类设计可用(msk modulation and demodulation process simulation using matlab, Communications design available)

使用误差累计的方式，来实时的更新背景，提取出最新的背景，(Cumulative manner using the error to the background of real-time update, extract the latest background)

图形用户界面（Graphical User Interfaces ，GUI）则是由窗口、光标、按键、菜单、文字说明等对象（Objects）构成的一个用户界面。用户通过一定的方法（如鼠标或键盘）选择、激活这些图形对象，使计算机产生某种动作或变化，比如实现计算、绘图等。(matlab gui)

用matlab实现瑞利信道的仿真，分析该信道下系统的误码性能(Rayleigh channel simulation using matlab, system error performance analysis of the channel)

Outage probability is a crude measure of performance. It is defined as the probability when mutual information is less than the given threshold. The importance of outage probability is that when outage occurs, there is more likely to have decoding failure. In other words, it is a typical error. In fading channels, the received signal has no constant power which be depending on the channel, can be described by probability models. Thus, signal to noise ratio will also becomes a random variable. and Thus the maximum capacity of the channel becomes a random variable. Outage probability says according to the variable signal to noise ratio at the received end, what is the probability that a rate is not supported due to variable signal to noise raito.
