Based on our previously developed signal perturbation free (SPF) transmit scheme, a new linear prediction (LP)-based channel estimation algorithm with ill condition identification is proposed for MIMO-OFDM systems. Based on the estimated correlation matrix of the received signal without signal perturbation error by employing the SPF transmit scheme, a SPF LP-based MIMO-OFDM channel estimation algorithm...
In this paper, a novel signal-perturbation-free (SPF) approach is presented for frequency-selective multiple-input-multiple-output orthogonal frequency division multiplexing channel estimation. First, an efficient transmit scheme, which bears partial information of the correlation matrix of the transmitted signal called SPF data, is proposed for the cancellation of signal-perturbation error at the...
The second-order statistics (SOS) of the received signal are very often used in blind and semi-blind channel estimation. In this paper, an analysis of signal perturbation in SOS of the received signal is first conducted, revealling that, even in the noise-free case, some SOS-based blind and semi-blind algorithms are subject to a signal perturbation error. Based on the analysis, a very efficient transmit...
