- W2377617935 abstract "The correlation among the Orthogonal Frequency Division Multiplexing(OFDM) subcarriers in the frequency domain is studied,and is used for subcarriers grouping.The number of coherent subcarriers is calculated according to the concept of coherent bandwidth,and is used to divide the subcarriers into groups.Average channel information within a group is proposed to represent the whole group.A simulation platform is established in Matlab to simulate the correlation among OFDM subcarriers in frequency domain.Simulation results show that it can greatly reduce the uplink feedback overhead,and do not result in the loss of system throughput performance when the group size is equal to the number of coherent subcarriers." @default.
