System-level simulator
is designed to simulate the complicated behaviors between a large number of base stations (BSs) and user equipments (UEs) in a mobile communication system, where links between BS and UE may interfere with each other. The intricate behaviors include traffic models, scheduling algorithms, CSI feedbacks, interference managements and so on. Therefore, the network performance of a mobile system including average spectrum efficiency, traffic impact, user packet throughput, latency, fairness, etc. can be evaluated in a comprehensive way.
Nowadays, system-level simulation has been used in equipment verification, network planning, and academic research. Besides, in the international communication standard organizations including 3GPP and ITU, system-level simulation is also widely used for specification developments of next-generation wireless communication networks.
