Wonjae Shin, Eu-Suk Shim, Byoung-Heon Lee, Jae-Hoon Yi, Young‐Hwan You

Abstract

In this paper, algorithms for synchronization of carrier frequency offset (CFO) are presented which use the preamble in OFDM-based 802.16 systems. To demonstrate the efficiency of the proposed scheme, the performance of the proposed CFO estimators is compared to that of conventional method in terms of mean square error (MSE) and acquisition range.
