The Research of LTE-R Handoff Algorithm Based on Fuzzy Prediction

With the rapid development of high-speed railway, LTE-R is a railway broadband mobile communication technology, which has become an inevitable trend. LTE-R is a next-generation broadband mobile communication system determined by the International Railway Union. It has some features such as high speed, low time, high mobility and high security. This paper analyzes the measurement parameters in the process of high-speed railway wireless communication environment and improves a handover algorithm based on fuzzy prediction. By optimizing the gray model and then pre-processing the measurement parameters, it effectively to reduce the number of ping-pong switching in the switching process and improve the switching rate under the condition of high speed.
