The invention discloses an aircraft information network time-frequency address pattern generation system and method, and the method comprises the steps: initializing time domain and frequency domain resources, mainly including time discretization and frequency discretization, and enabling the discretized time-frequency domain resources to form a time-frequency address pattern; performing program simulation, querying the current moment, recording the moment, judging whether a service is sent or not, if not, continuing to query the moment, and if yes, performing signal transmission; and carrying out parameter statistics, judging whether the parameter meets an initially set threshold condition, if the condition is not met, regenerating a new time-frequency address pattern until the parameter meets the condition, and outputting the time-frequency address pattern. The invention solves the technical problem of generating the time-frequency address pattern of the aircraft information network, which utilizes a time-hopping and frequency-hopping method to reduce the channel conflict probability and realize the simultaneous optimization of time-domain and frequency-domain resources under the condition that the time-frequency resources are limited.
Description
technical field [0001] The invention belongs to the technical field of wireless network and communication, in particular to a system and method for generating a time-frequency address pattern of an aircraft information network. Background technique [0002] In the information network planning, each node is assigned a receiving address (time-frequency pattern); in the operation of the information network, the destination node is obtained by the network layer query and transmission in each information transmission, and the link layer correspondingly obtains the corresponding destination address; the information network link The physical layer sends the destination address and transmission information to the physical layer. The physical layer processes the transmission information, and completes pulse formation and pulse transmission control after obtaining the transmission signal. The address is captured to obtain the transmission signal, and the captured pulse train is sent t...
