Abstract: A blind scheme to estimate frequency-domain channel response (is also called channel frequency response,CFR) in single-input multiple-output (SIMO) single-carrier frequency-domain equalization (SGFDE) systems based on linear prediction algorithm(LPA) was presented. Compared with conventional LPA based time-domain channel estimation approach, this method obtains the closed-form solution for channel estimation in frequency-domain directly from tap weights of the prediction filter, rather than Cross-correlation of innovation and measurements. It exploits merely seconBorder statistics(SOS) , and is robust to channel order overestimation. Furthermore, the performance of the proposal is better than conventional LPA based timcdomain channel estimation approach. Finally, computer simulations confirm the theoretical analysis.
