Liu Yuan-tao · Signal Processing · 2008
This paper proposes a robust blind channel identification and equalization algorithm.The channel order is estimated ex- actly first by the improved estimation method on the condition that the channel order upper bounder is known,compared with the existing methods,which works well on lower SNR in more channels.Then,the eigenvalue perturbation analysis is been done on the basis of matrix outer-product decomposition to get the more superior performance of channel blind identification and equalization.Simulation results prove the efficiency of the new identification algorithm.
