ATLAB是矩阵实验室（Matrix Laboratory）的简称，是美国MathWorks公司出品的商业数学软件，用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境，主要包括MATLAB和Simulink两大部分。(ATLAB is a matrix laboratory (Matrix Laboratory) for short, is a U.S. company produced a commercial mathematics MathWorks software for algorithm development, data visualization, data analysis and numerical calculation of the senior technical computing language and interactive environment, including MATLAB and Simulink two parts.)

Recently, both to return to my old love for evolution and to broaden my research horizon, I have started working on models simulating the dynamics of evolutionary processes. It is becoming clearer and clearer in biology that to understand form,

说明：  Matlab开发，可以和Access数据库连接，实现成绩查询(Matlab development, Access database connection can achieve results query)

COFDM系统在不同调制方式（BPSK/QPSK/16PSK）下的PPCR和BER的比较。不含噪声和多径(COFDM modulation system in different ways (BPSK/QPSK/16PSK) under the PPC R and BER comparison. Without noise and multipath)

一种系统辨识方法。对汉默斯坦ARX模型未知参数的系统辨识(Hammerstein MISG algorithm for Hammerstein ARX models)

就是自适应的一写程序(is an adaptive process to write)

用于图像分块，将图像分为大小一致的图像，便于图像像素位置的确定(For the image block, the image into an image of the same size, easy to determine the location of the image pixel)

MATLAB是美国MathWorks公司出品的商业数学软件，用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境，主要包括MATLAB和Simulink两大部分。(MATLAB is a commercial mathematical software produced by MathWorks company for the United States, senior technical computing algorithm development, data visualization, data analysis and numerical computing language and interactive environment, mainly includes two parts of MATLAB and Simulink.)

说明：  目前，以空间调制(Spatial Modulation，SM)、广义空间调制(Generalized Spatial Modulation，GSM)为代表的新型MIMO技术，成为4G以及5G的关键技术。空间调制系统在一个符号周期内，发送端只选择部分发送天线发送信号，从而大大提高了频谱效率，是大规模MIMO系统的重大突破。(At present, the new MIMO technology represented by spatial modulation (SM) and generalized spatial modulation (GSM) has become the key technology of 4G and 5g. In a symbol period, the transmitter only selects part of the antenna to transmit the signal, which greatly improves the spectral efficiency. It is a major breakthrough in large-scale MIMO systems.)
