- Abstract:
-
In view of the problem of the temporal redundaney in temporally-correlated MlMO channels, a newlimited feedback approach based on channel predietion is proposed in this paper. Both the temporal cohereneeof the adjaeent data frames and AR prediction model are used to prediet channel state information and find anoplimal eodeword which is utilized to get an integrated oplimal system performanee of data frames and feedbackit to sender. The simulation results show, while the system performanee of the feedback approach proposed hasdeereased compared with the traditional one, but the feedback costs are signifieantly redueed, so the performanee loss is acceplable.
