在多用户M IMO系统中, 基于信漏噪比( SLNR)的预编码由于同时消除了共信道干扰( CC I) 和噪声而提高 了系统性能。-In multi-user M IMO system, based on the letter to noise ratio (SLNR) leakage of precoding because while eliminating cochannel interferences (CC I) and noise and improve The system

偏最小二乘法，能很好建立物质浓度和与相应的光谱矩阵的回归方程，且能对光谱阵降维和消除噪声影响。-Partial least squares, to establish material concentration and good with the regression equation of the corresponding spectral matrix array dimensionality of the spectrum and can eliminate noise effects
