Abstract

Wireless communication is the key area of research with increasing demand of high data rate applications at a low cost. Orthogonal Frequency Division Multiplexing (OFDM) is a promising solution for this problem. It is a multi carrier modulation and as well  as a multiplexing technique proposed for 3G, 4G, LTE-A systems to support high data rate applications in a fading environment. Many problems linked with the multi carrier transmission like phase variations and Carrier Frequency Offset (CFO) are prominent. In this paper we analyze CFO and its effect in detail for OFDM symbol and then describe techniques to estimate CFO. The estimation techniques cover both domains; time and frequency for OFDM system. The simulations results are analyzed and presented in this paper are performed in MATLAB.
