matlab程序占用内存情况 注意：并非matlab中的变量占用内存情况(How many memory does Matlab Program used. It is not variables used memory.)

说明：  本程序主要是为初学者提供，里面介绍了怎样用MATlab观察一个信号的波形 星座图 频谱 等(this program is to provide beginners. on the inside with what MATlab observation of a signal waveform constellation spectrum)

像差分析，对像差进行模拟仿真，进行光学设计和像差校正(wavefront abberation analysis)

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.)

Dear Sir, I have uploaded some neural network and DSP kind of programms. Thank You, -bibyut

MIMO线性预编码研究，破零算法和块对角化算法比较(Pre coding MIMO linear, breaking the zero algorithm and the block diagonalization algorithm comparison)

Generation of AWGN as a function of ExN0

说明：  L-曲线法是反问题正则化方法中的参数选取中的重要方法，本程序给出了如何恰当选取其中的参数！(L-curve method is the inverse problem regularization method of parameter selection in an important way, this procedure is given on how to properly select one of the parameters!)

说明：  这是一本电力电子与电力拖动的仿真教程，相对来说讲的比较详细，也比较全面。(This is a drag power electronics and power simulation tutorial, relatively speaking in more detail, but also more comprehensive.)
