Abstract : Orthogonal Frequency Division Multiplexing (OFDM) systems are particularly sensitive to carrier frequency offset (CFO) and Inphase and Quadrature (I/Q) imbalance. These parameters degrade the performance of OFDM-based system as they destroy the orthogonality between sub-carriers. In this paper, we designed an estimation algorithm which is based on non data aided technique for the CFO and I/Q imbalance by taking advantage of the inherent orthogonal structure in the OFDM signal. We particularly analyze the different standards of 802.11, the wireless local area network (WLAN) that are OFDM based to evaluate the performance of this algorithm. The simulation results show the improvement of new estimator over the existing one in the presence of I/Q Imbalance.
