A Review on Various OFDM Techniques and Their Applications

Anjali Saxena, Surbhi Kaushik

Abstract: Orthogonal frequency-division multiplexing (OFDM) effectively mitigates intersymbol interference (ISI) caused by the delay spread of wireless channels. Therefore, it has been used in many wireless systems and adopted by various standards. In this paper, we present a comprehensive survey on OFDM for wireless communications. We address basic OFDM and related modulations, as well as techniques to improve the performance of OFDM for wireless communications, including channel estimation and signal detection, time-and frequency-offset estimation and correction, peak-to-average power ratio reduction PAPR, intercarrier interference (ICI) and multiple-input–multiple-output (MIMO) techniques. We also describe the applications of OFDM in current systems and standards.

Keywords: Channel estimation, frequency-offset estimation, intercarrier interference ICI, multicarrier MC, multiple inputmultiple-output MIMO orthogonal frequency-division multiplexing OFDM, peak-to-average power reduction, timeoffset estimation, wireless standards
