Wiener Filter based Channel Estimation Using Superimposed Pilot

Abstract (in Japanese) (See Japanese page) 
(in English) Superimposed pilot-aided channel estimation (SI-PACE) has a potential of high tracking ability against channel variation due to fading, but interference from data channel degrades the accuracy of channel estimation. The interference from data channel can be reduced by taking simple time averaging of the superimposed pilot, but the tracking ability tends to be lost. In this paper, we propose a Wiener filter based SI-PACE which can suppress the interference from the data channel while achieving a high tracking ability. We investigate by computer simulation the bit error rate (BER) performance of single-carrier (SC) and orthogonal frequency-division multiplexing (OFDM) using the Wiener filter based SI-PACE in a frequency-selective Rayleigh fading channel.
