Abstract

Frequency Domain Equalization (FDE) is an attractive solution for wireless broadband transmission because of its strong capability in handling multipath environment. However, frequency domain channel estimation suffers from the inter-carrier interference(ICI) caused by carrier frequency offset (CFO). In this paper, we proposed new training sequence structure for channel estimation to reduce the estimation errors caused by residual CFO. The proposed new training sequence structure can be easily obtained from any existing channel training sequences without introducing significant changes to their original property. Simulation results show that, this scheme can efficiently reduce the channel estimation errors in FDE system, and improve the system performance.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
