Abstract

A least square (LS) channel estimation with pilots uses interpolation to obtain the channel information for the positions of data subcarriers in orthogonal frequency division multiplexing (OFDM) systems. However, the interpolation introduces estimation errors in long delay channels that usually happen in single frequency networks (SFNs). In this paper, we propose an algorithm that estimates the accurate channel information by separating channel paths. The performance is compared with conventional algorithms for DVB-T in SFN conditions.
