MATLAB人体行为异常识别
说明： 本文设计了一款人体行为异常监控系统，主要适用人群是老年人，在摄像头固定的情况下，自动检测人体运动轨迹，并与提前设定好的行为库进行匹配，分析判断是否具有异常行为。
在数字图像预处理部分采用了图像二值化，腐蚀与膨胀等几种方法为人体目标的跟踪和检测做准备。为了克服在实际操作中遇到的问题，采用了帧差法和ViBe算法，帧差法即利用帧间变化与当前帧、背景算法来判断它是否大于阈值，并分析视频中序列的运动特性，ViBe算法则是一种背景建模的方法，背景模型是由邻域像素来创建，并对比背景模型、当前输入像素值检测出前景，确定视频中的目标跟踪。在人体行为识别中，运动目标最小长宽比以及连续帧间的加速度来判断人体行为是否异常，如果检测到异常的行为比如说摔倒、快跑等行为，在识别的过程这种实时监测。不同环境可能需要调试，要求有一定编程基础，小白慎入。(In this paper, a monitoring system for abnormal human behavior is designed, which is mainly applicable to the elderly. When the camera is fixed, it can automatically detect the human motion track and match with the behavior database set in advance to analyze and judge whether there is abnormal behavior.)

Additionally, LTE supports operation both in paired and unpaired spectrum (FDD and TDD) using channel bandwidths of approximately 1.4MHz up to 20MHz. The frequency domain scheduling can be done in OFDMA. One of the main challenges in OFDMA is the high peak-to-average radio of the transmitted signal, which requires linearity in the transmitter. The linear amplifiers have low efficiency therefore, OFDMA is not an optimized solution for a mobile uplink where the

直接序列扩频（Direct Sequence Spread Spectrum）工作方式，简称直扩方式（DS方式）。就是用高速率的扩频序列在发射端扩展信号的频谱，而在接收端用相同的扩频码序列进行解扩，把展开的扩频信号还原成原来的信号。(irect Sequence Spread Spectrum (Direct Sequence Spread Spectrum), hereinafter referred to as Direct expansion mode (DS). Is a high rate of spread spectrum sequence extension in signal spectrum, and at the receiving end with the same spread spectrum code sequence for expansion, the expansion of the spread spectrum signal back into the original signal. )

A MIMO multiplexing system with NT transmit and NR = NT receive antennas is designed.
The main challenge for MIMO systems lies in the non-orthogonality of the transmission channel.
This can be solved by turbo processing.
Turbo channel encoder is used for converting the bits in its suitable form.
Then different M-ary QAM is compared.
