SLM（selected mapping）是正交频分复用中用于减少系统峰平比的方法。(SLM (selected mapping) is orthogonal frequency division multiplexing system used for PAPR reduction method.)

对北大西洋1980-1999的月均SST资料进行EOF分解(EOF the sea surface temperature of north atlantic in 1980-1999)

说明：  Nakagami-m分布能用来对比瑞利分布条件更苛刻的衰落信道进行建模，最适合于郊区无线多径信道上接受的数据信号，瑞利分布是它 时的特例。(Nakagami-m distribution can be used to model fading channels with more stringent Rayleigh distribution conditions. It is most suitable for data signals received on suburban wireless multipath channels. Rayleigh distribution is its special case.)

1、 从网上下载人脸图像，构建人脸训练数据库和测试数据库，采用K-L变换进行特征脸提取，并实现人脸识别。通过K-L变换在人脸识别中的应用，加深对所学内容的理解和感性认识。(1, face image downloaded from the Internet, the construction of the training and test database face database, using K-L transform features face extraction, and realize the face recognition. Through k-l transform in face recognition application, deepen the understanding of the content of study and perceptual knowledge.)
