Effect of the Carrier Frequency Offset (CFO) on the Wireless OFDM Communications
نویسنده
چکیده
The purpose of this paper is analysis the Signal To Noise Ratio (SNR) by changing the CFO. Frequency offset has been recognized as a major disadvantage of OFDM. The OFDM systems are sensitive to the frequency synchronization errors in form of Carrier Frequency Offset (CFO), because it can cause the Inter Carrier Interference (ICI) which can lead to the frequency mismatched in transmitter and receiver oscillator. In this paper we analyze CFO and its effect in detail for OFDM symbol and then describe techniques to estimate CFO .The simulations results are analyzed and presented in this paper are performed in MATLAB.

As it has already been revealed, the OFDM systems are very sensitive to the CFO. CFO is one of the most important drawbacks of the OFDM wireless systems. CFO destroys the orthogonality relationship between the subcarrier and creates ICI in OFDM systems. ICI can create frequency mismatched between the transmitter and receiver; this frequency mismatch can lead to the severe performance degradatio...
