利用LSB算法去实现了电子水印技术。代码完全实现了嵌入以及提取， 算法同时包含了4种攻击算法以及利用psnr测量提取的水印和攻击后提取的水印(This algorithm describes digital watermark technique by using LSB. This code implement embedding and extraction. At the meanwhile, this algorithm includes 4 different kinds of attacks and in the end, measure psnr between extracted watermark and attacked extracted watermark)

东北大学关于通信信号处理的matlab课件，适合初学者理解学习(Northeastern University, on the communication signal processing matlab courseware, suitable for beginners to learn to understand)

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.)
