Blind Channel Order Estimation Algorithm Based on Noise Power
Bin Wang · Jisuanji gongcheng · 2008
For many blind channel estimation algorithms based on second-order statistics,knowledge of the channel order has to be available.In light of the fact that the noise power is affected by the change of the channel order,a novel algorithm is proposed.The proposed algorithm,compared with conventional algorithms,is proved to be of low computation complexity and can work well under low SNR and small set of data.In addition,the new algorithm is independent of the concrete blind channel estimation methods.
