Analysis of Orthogonal Frequency Division Multiplexing for Wireless Communication System | Original Article

ABSTRACT:

Nowadays-Orthogonal frequency division multiplexing is the transfer of two signals it means that the two coexisting signals are independent of each other in a time interval. OFDM is a multi-carrier modulation technique with densely spaced sub-carriers that has gained a lot of popularity among the broadband community in the last few years. OFDM has been shown to be an effective technique to combat multipath fading in wireless communications. It has been successfully used for HF radio applications. OFDM has chosen as the standard for digital audio broadcasting and high-speed wireless local areas networks. In this Paper, we present different literature including introduction to OFDM Modulation its advantages and demerits, and some applications of OFDM. OFDM Techniques for peak-to-average power ratio reduction, time and frequency synchronization, and channel estimation will be discussed. We conclude with a brief overview of current application areas.
