Abstract

As we know, synchronization issues are of great importance in OFDM receiver especially symbol timing offset synchronization. Synchronization errors not only cause inter-symbol interference (ISI) but also introduce inter-carrier interference (ICI) duo to the loss of orthogonally among all sub-carriers. In this paper, we proposed an improved method which can not only get better estimation performance but also decrease computation complexity that never needs any analogy timing loops for better ASIC area cost and power consumption.

Keywords: OFDM synchronization symbol timing offset
