Abstract :
An efficient DFT-based frequency offset estimation technique is presented for orthogonal frequency division multiplexing (OFDM) digital communication systems. The performance of the proposed scheme is confirmed by computer simulation for 16-QAM signals with class I Rife and Vincent windows
