说明：  SVM Multiregression for Non Linear Channel Estimation in Multiple-Input Multiple-Output Systems 在多输入多输出系统中的SVM多元回归非线性逼近
(This paper addresses the problem of Multiple-Input Multiple-Output (MIMO) frequency non-selective channel estimation. We develop a new method for multiple variable regression estimation based on Sup- port Vector Machines, a state-of-the-art technique within the machine learning community for regression estimation. We show how this new method, that we call M-SVR, can be effi ciently solved. The pro- posed regression method is evaluated in a MIMO system under a channel estimation scenario, showing its benefi ts in comparison to previous proposals when non linearities are present in either the transmitter or the receiver sides of the MIMO system.)
