Frequency Offset Estimation for OFDM Systems with a Novel Frequency Domain Training Sequence
A novel frequency domain training sequence and the corresponding carrier frequency offset (CFO) estimator are proposed for orthogonal frequency division multiplexing (OFDM) systems over frequency-selective fading channels. The proposed frequency domain training sequence comprises two types of pilot tones, namely distinctively spaced pilot tones with high energies and uniformly spaced ones with ...
متن کاملA Novel Frequency Offset Estimation Scheme for OFDM Systems
In this paper, we propose a novel frequency offset estimation scheme for orthogonal frequency division multiplexing (OFDM) systems. By correlating the OFDM signals within the coherence phase bandwidth and employing a threshold in the frequency offset estimation process, the proposed scheme is not only robust to the timing offset but also has a reduced complexity compared with that of the conven...
متن کاملCarrier Frequency Offset Estimation in Ofdm Systems
Orthogonal Frequency Division Multiplexing (OFDM) is multicarrier modulation scheme for combating channel impairments such as severe multipath fading and impulsive noise. However, the principal disadvantage of OFDM is that it is highly susceptible to carrier frequency offset (CFO). Carrier frequency offset occurs due to frequency discrepancies between transmitter and receiver and Doppler shift ...
متن کاملA Novel Approach of Frequency offset Estimation for OFDM System
Orthogonal frequency division multiplexing(OFDM)has recently attracted vast research attention from both academia and industry and has become a part of new emerging standards for broadband wireless access. Synchronization at receiver end represents one of the most challenging issues and plays a major role in physical layer design.This paper presents design and implementation of a Channel estima...
متن کاملEfficient Carrier Frequency Offset Estimation in OFDM Systems by Using Periodic Training Sequence
Periodic training sequence based carrier frequency offset estimate in orthogonal frequency division multiplexing (OFDM) systems is discussed. By exploiting the independent conditional Probability Density Functions (PDF) of different sub-blocks in a received training sequence, a new complexity efficient carrier frequency offset estimator is proposed. The same accuracy as that of Best Linear Unbi...
