Abstract: In view of the current LTE data transmission network optimization algorithm to judge the channel transfer efficiency is low, bandwidth occupancy rate is high, it is difficult to improve the stability of the data through lack of data transmission quality, proposes a LTE data transmission network optimization algorithm based on TDMA fluctuation tracking mechanism; first based on TDMA (Time Division Multiple Access, TDMA) control mode, and combined with the Markoff channel transfer model, optimize the channel bandwidth migration trajectory, improve the efficiency of the algorithm for the channel in the first emission signal; then based on the non - channel excited excited state channel transfer probability acquisition way, build ups tracking mechanism, can through the screening of the fluctuation characteristics of the channel transfer further, improve the efficiency of data transmission algorithm, and can effectively reduce the channel error phenomenon. Simulation results show that with the current LTE network data transmission in common with carrier mixing through the filter algorithm (Hybrid Carrier Band Pass Filtering Algorithm) and narrowband noise adaptive filtering algorithm (Adaptive Filtering Algorithm for Narrowband Noise Regulation) phase ratio, this algorithm can effectively reduce the minimum bandwidth required for data transmission and improve the transmission performance of the channel, and the data transmission quality is high and has obvious practical value
