Kalman Filter Based Sliding Window Approach For Optimized Link Control In 4G Wireless Network

This paper presents smart link control scheme for wireless networks based on Kalman filter-sliding window controller. The scheme aims at improving the controller adjustment and the network link quality by selecting the optimal modulation and coding scheme for data transmission. The scheme is designed and implemented using MATLAB and evaluated through simulation. The results show that the new system with smart link control achieves better performance in terms of throughput, spectral efficiency, and bit error rate than the conventional link control schemes. In addition, it reduces the probability of using more robust modulation and coding schemes by the Radio Link Control entities, thus increasing the data rate and the resource utilization of the network.
