Joint Allocation of Bandwidth and Power in Multi-Service Scenarios in DVB Systems

This paper focuses on the dynamic allocation of power and bandwidth resources by the DVB-RCS system under multi service scene. Firstly, it analyzes the shortcomings of existing multi service queue scheduling strategy and proposes an improved scheme for multi user scheduling policy, which calculates and schedules the user's business and channel environment firstly, then the users' bandwidth and power are distributed together according to the calculation results and the simulation of the algorithm is implemented on the OPNET simulation platform. Finally, we verify the algorithm for the protection of the QoS delay through simulation and compare the impact of algorithms on resource allocation under conditions of different business capacity requests and different channel conditions on resource allocation.
