Abstract

Compared with channel estimation method based on explicit training sequences bandwidth is saved for those methods using superimposed training sequences while it is wasted when Cyclic Prefix CP is added In previous work of McLernon the Mean Square Error MSE performance of DataDependent Superimposed Training DDST without CP for SingleInput SingleOutput SISO system was analyzed under the assumption that the datadependent sequence matrix was a circulant matrix and not interfered by others In fact for the system without CP the datadependent sequence matrix is not circulant any more and will be interfered This paper derives the exact expression of MSE for the system without CP and also gives its extension to MultipleInput MultipleOutput MIMO system without CPSupported by the National Natural Science Foundation of China No 60772087 No 50803016 No 60975004 No 60902023 the Foundation for the Author of National Excellent Doctoral Dissertation of P R China No 200341 the National 863 HighTech RD Program No 2007AA01Z 228 and the open research fund of Key Laboratory of Information Coding and Transmission Southwest Jiaotong University
