In order to solve the problems of low channel transfer efficiency, high bandwidth utilization and difficult to improve data transmission quality in the current LTE network data transmission optimization algorithm, a new LTE network data transmission optimization algorithm is proposed. Based on time division multiple access (TDMA) control technology, the channel bandwidth offset is optimized combining with Markoff channel transfer model. The ups and downs tracking mechanism is constructed by obtaining channel transition probability of excited state and non-excited state, and the fluctuation characteristics in channel transfer are selected. Simulation results show that the proposed algorithm has the lowest bandwidth required for data transmission, higher data transmission quality and better channel transmission performance compared with the hybrid carrier band-pass and narrowband noise adjustment adaptive filtering algorithm in the current LTE network data transmission.
