Methods for Compression of Feedback in Adaptive Multi-Carrier 4G Schemes
Paper in proceedings, 2007
In this paper, several algorithms for compressing
the feedback of channel quality information are
presented and analyzed. These algorithms are developed
for a proposed adaptive modulation scheme for future
multi-carrier 4G mobile systems. These strategies compress
the feedback data and, used together with opportunistic
scheduling, drastically reduce the feedback data rate. Thus
the adaptive modulation schemes become more suitable
and efficient to be implemented in future mobile systems,
increasing data throughput and overall system performance
as compared to wired systems ten years ago.
