Summary:This paper presents some evaluation methodologies for a B3G system adopting OFDMA as its multiple access method from system level's point of view. A system level simulator is established to assess the performance of the B3G system based on OFDM or multi-carrier technology. The introduction of these technologies leads to some different simulation methods including channel model, link to system interface, etc., and some special radio resource management schemes including multiple access, power control, packet schedule, handover, etc., compared with the previous system. We analyse the rationality of these modelling methods, and their limitations as well. Some special and novel RRM algorithms for OFDM are discussed and implemented into the basic platform. The simulator and proposed algorithms are justified by the presentation of collected results derived from the simulator
