Noise space based blind channel estimation for OSTBC OFDM

SONG Zheng-wei,ZHAO Min-jian,ZHONG jie,QIU Pei-liang(Department of Information Science & Electronic Engineering,Zhejiang University,Hangzhou 310027,China)  
A blind channel estimation technique based on noise space for multiple-input multiple-output(MIMO) orthogonal frequency division multiplexing(OFDM) systems was presented.The method can be applied to some kinds of orthogonal space-time block code(OSTBC) with coding rate smaller than 1 and utilizes only the orthogonality and redundancy introduced by themselves.The singular value decomposition(SVD) method was used to get the noise space and channel impulse responses(CIRs) with ambiguity which was resolved by some pilots.Conditions for the existence of noise space decomposition were discussed.Some considerations were proposed to reduce computational complexity by decreasing the dimension of the objects of SVD.Numerical results illustrate the mean-square error performance and symbol error rate of the method.
