Title

A Review on Carrier Frequency Offset Estimation in OFDM Systems

Authors

Abstract

This paper is a review of the various techniques for carrier frequency offset (CFO) estimation in orthogonal frequency division multiplexing (OFDM). The performance of OFDM system is much sensitive to CFO, which causes inter-carrier interference (ICI). In cyclic prefix (CP) based estimation, the CFO can be estimated from the phase angle of the product of CP & corresponding end part of the OFDM symbol. In CFO estimation using training symbol, the CFO estimation range can be increased by reducing the distance between two blocks of samples for correlation. This was made possible by using training symbol that are repetitive with shorter period. Bit Error Rate vs Signal to Noise Ratio & mean square error (MSE) are the some characterization parameters of the system to observe the effects of frequency offset synchronization.

Key Words

Orthogonal Frequency Division Multiplexing (OFDM), Carrier Frequency Offset (CFO), Inter-Carrier Interference (ICI).
