| description | The invention discloses a rail traffic train-to-train communication method based on space-time division multiple access. The method comprises the steps of firstly, determining the position and speed information of each train through a transponder, a speed sensor and wireless positioning equipment, dividing a same-frequency channel of train communication into a plurality of time slots in a time division multiplexing mode, combining the relationship between the position of each train and a kilometer post, numbering trains, each train occupying one time slot, and after all the trains occupy the time slots, enabling all the time slots to circularly occur in time, so that in a certain distance range, same-frequency interference between the trains is avoided, and direct communication between the trains can be realized. By multiplexing and combining the time slots, the utilization rate of the time slots is increased, and frequency resources can be greatly saved. Meanwhile, the method can be combined with a current C |
