The Research On The System Level Simulation Of MC-CDMA

3G system is considered as a middle-system between narrow band mobile communication system and the future system, because its core network is mostly the same as 2G. More and more attentions have been paid on the Beyond 3G mobile communication system recently, it can provide larger capacity, higher data rate and better communication performance.The development on Orthogonal Frequency Division Multiplexing (OFDM), Multi-Input Multi-Output(MIMO),Adaptive Modulation and coding, and Adaptive ARQ will make a groundwork for the commercialize of B3G.However, in face of the more complex service and richer wireless resource, we need to propose more efficient algorithm to manager the wireless resource, and improve the system QoS based on the fixed physical layer technology. But as there isn't an agreement with the B3G system framework, say nothing of validating the Radio Resource Management(RRM) in a real system, so we have to do research on the framework of future mobile communication system, build an efficient and reasonable model to validate the RRM.In this paper, we propose a framework of the future MC-CDMA system, make a brief introduction of RRM that may be used in MC-CDMA, and also make a deep research on the key problem of system level simulation. Then we develop a system level simulation platform base on c/c++, which aims to validate the performance of some key parameter of mobile cellular system and RRM.
