OFDM-MIMO based carrier frequency offset modulation for the multi-carrier transmission

In this paper a hybrid framework has been developed which is based on OFDM-MIMO system. This system adopted carrier frequency offset (CFO) modulation scheme for the multi-carrier transmission. Different subcarriers have been considered with quadrature amplitude modulation (QAM). Different channel capacity along with the subcarrier and lengths have been considered for the system performance estimation. CFO with different channel consideration is found to be helpful in the improvement of the system. The results show the variations in subcarrier, length and variations. The results show the improvement in bit error rate (BER) in case of increasing the number of systems, subcarriers and variations in correlation.
