Abstract
In order to achieve large-scale positioning by the ground positioning base station network, the mode of co-address and co-frequency broadcasting between the positioning base station and the existing communication base station can be considered. Under this circumstance, in order to meet the need of ultra-dense networking of integrated communication and navigation system, an optimized cellular positioning networking scheme is proposed in this paper. In the outdoor complex transmission environment, the boundary conditions that the proposed cellular network model needs to meet are analysed for the TC-OFDM system. Besides, based on the greedy algorithm of quadratic optimization, the spreading codes with better performance are selected for the reuse of cellular network modules. Theoretical analysis and simulation results show that the optimized cellular network model can well meet the large-scale positioning requirements of integrated communication and navigation system, and the selected spreading code has better performance.
