CALIBRATION FOR CHANNEL SIMULATOR

摘要

PROBLEM TO BE SOLVED: To provide a method that is applied to a large-capacity channel simulator having interfaces of P base stations and Q terminals so that path loss calibration for P*Q paths is performed.SOLUTION: A calibration method for a channel simulator that forms channels with respect to all paths between P base stations (P is an integer more than 2) and Q terminals (Q is an integer more than 2) comprises: a base station power calibration step of equally maintaining P ADC powers of base station interface cards of the channel simulator; and a terminal path loss calibration step of equally maintaining Q DAC powers of terminal interface cards of the channel simulator in a state that one base station subject to the power calibration is connected with the Q terminals.SELECTED DRAWING: Figure 3
