Dynamically-variable resource allocation method for MF-TDMA (Multi-Frequency Time Division Multiple Access) satellite communication system

The invention discloses a resource allocation method with a dynamically-variable modulation coding mode for an MF-TDMA (Multi-Frequency Time Division Multiple Access) satellite communication system. The technical scheme of the method comprises the following three steps: firstly, allocating different link applications to different carriers according to the traffic of each link application; secondly, continuously adjusting the modulation coding mode of each link application to increase the overall system capacity, and determining a time slot needing to be allocated to each link application according to a carrier rate and the modulation coding mode allocated for each link application; lastly, allocating a specific time slot for each link application in the channel structure of the MF-TDMA satellite communication system by adopting a Best-Fit algorithm to finish the entire resource allocation process. Compared with the prior art, the method has the advantages that the system capacity is increased, and the reject
