Channel prediction, which predicts a future channel gain based on current and past observations, is very useful for power control and resource optimization in wireless communication systems. However, a low-complexity predictor with trustworthy prediction accuracy is yet to be developed. This paper proposes a linear predictor and two linear Markov predictors, which achieve a good balance between complexity...
World Wide Web is growing rapidly. So it is necessary to study the user web navigation behavior to improve the quality of web services, offered to the web user. Analysis of user web navigation behavior is achieved through modeling web navigation history. Markov model is widely used to model the user web navigation sessions. Lower-order Markov model provides high coverage, but with low accuracy. Higher-order...
