OFDM链路级的仿真器场景是单小区单用户，信号从发送端发送，在接收端进行信号估计。估计误差可以从接收和发送信号的不同得到。仿真器的输出是BLER/BER vs SNR。(OFDM 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。)
