Channel parameter extraction methodology for system-level simulator in small cell environments

Small cell networks have many attractive solutions to solve the network overload caused by heavy demands of traffic. To evaluate the performance of systems, a system-level simulator (SLS) is typically used. However, the performance evaluation with a typical channel parameter set which is representing the entire area in SLS shows only the typical performance of the entire area, so that extra field trial is necessary to evaluate realistic deployment performance of a given region. In this paper, a channel parameter extraction methodology is proposed by using a ray tracing tool to evaluate a realistic performance of a target region for SLS.
