چکیده

In wireless communications systems, Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) are used to improve spectral efficiency and spatial diversity. Beamforming is used to improve bandwidth utilization. It increases the network range in wireless systems. The main challenge of OFDM system is Carrier frequency offset (CFO). The project focuses on CFO estimation technique to compensate for the effect of CFO on OFDM system. Carrier Frequency Offset estimation are used to improve the efficiency of MIMO-OFDM system.
