| Abstract(in English) | A diversity scheme with fractional sampling (FS) in OFDM receivers is investigated recently. When a sharp filter is employed, the correlation of noise samples among the adjacent subcarriers increases, and the performance of this scheme is deteriorated. Therefore, low-complexity subcarrier based MMSE combining schemes with the subblock of the noise covariance matrix are proposed in this paper. Numerical results through computer simulation show that the MMSE combining schemes proposed in this paper can outperform a conventional MRC scheme and a subcarrier based MMSE combining scheme, when the sharp filter is employed. |
