Frequency Offset Compensation In OFDM System Using Neural Network

Rachana P. Borghate, Suvarna K. Gosavi

Orthogonal Frequency Division Multiplexing (OFDM) finds various applications in wireless communications. This paper proposes a technique for compensating the effect of the carrier frequency offset (CFO) in the orthogonal frequency division multiplexing (OFDM) systems using neural networks. OFDM systems are very sensitive to frequency offset due to Doppler shifts and carrier synchronization errors. Results will be show that using the proposed technique to compensate the CFO in OFDM system..
