Abstract：The calibration equipment of MIMO channel path parameter is made up of modular instruments, and using channel estimation techniques, the frequency response of MIMO channel is measured. Then the program that calculate the relative path delay is designed in order that the quantity of path parameter of MIMO channel simulator is calibrated. The calibration system is traceable by using the standard network which is made of delay line. According to experiment results, the range of measuring relative path delay is up to 5 000 ns. At 500 MHz frequency point, indicating value error of relative path delay is not more than 56 ns delay resolution from 291 ns to 585 ns.
