LTE-Advanced系统中一种基于模糊迭代的自优化算法

he 3G evolution system which is represented by LTE implement a revolutionary change, and new concepts and system designing based on OFDM technology greatly improved the system communication capacity .In fact LTE is regarded as the beginning to the next system LTE-advanced evolution more than a 3G evolutionary system.Concurrently, all kinds of video applications merged into out daily life more and more with the enhancement of transport bandwidths. However, VOD as an important application is limited by the system transportations because of the time-varying characters of wireless channel and the lacks of wireless resources. So the wireless systems can’t guarantee the QoS of video transportation. How a multi-user cellular system implements the optimal distributions and insures the user’s QoS in condition of guaranteeing user’s fairness and obtains the max throughput is the aim of a proper scheduler and it’s also the problem that we will study in the paper.
