应用背景This is the first time this simulator is published. We have tried to verify this simulator many times, however, there might still be some bugs. Please let us know if you found them. Thanks a lot. It contains mainly two parts, i.e. link-level simulator and system-level simulator. Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation. System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.关键技术 主要描述了单个小区和多个小区时（19）小区，包括主小区和18个相邻小区的链路
