基于OFDM的無線寬帶系統(tǒng)仿真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.
