چکیده
The wireless system for communication uses the orthogonal frequency division multiplexing in these days. The rapid growth of high data rate transmission makes a need to improve the performance of a network. This can be made easy by using Orthogonal Frequency Division Multiplexing. OFDM is an approach in which the multicarrier transmission technique has been used for wireless communication. Here the high data rate has been use to transmit the data. This high data can be divided into various sequences of the data. However, OFDM is sensitive to the receiver synchronization errors such as carrier Channel offset (CCO) that causes inter carrier interference (ICI), and exacerbated by motion-induced Doppler shifts and local oscillator instability. This paper gives a bird eye over OFDM , channel and frequency offset estimation and their recent
