Modeling and Analysis of Differential CQI Feedback in 4G/5G OFDM Cellular Systems

Reduced feedback schemes are crucial in achieving the high data rates expected of orthogonal frequency-division multiplexing-based 4G and 5G cellular systems. They ensure that the feedback overhead required for acquiring the channel-state information to enable downlink scheduling and adaptive modula...
