Orthogonal frequency division multiplexing (OFDM) is used for high speed communication but carrier frequency offset (CFO) creates problem in the working of OFDM and introduces loss of orthogonality between the subcarriers and gives rise to Inter Carrier Interference (ICI). The main causes of ICI are instability of local oscillators and Doppler affect. For the solution of CFO problem, self cancellation...
Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input and Multiple Output (MIMO) are two main techniques employed in 4th Generation Long Term Evolution (LTE). In OFDM multiple carriers are used and it provides higher level of spectral efficiency as compared to Frequency Division Multiplexing (FDM). In OFDM because of loss of orthogonality between the subcarriers there is intercarrier...
