Abstract


  • In this paper, two calibration methods are investigated to determine the most suitable approach for

    ultra-wide band (UWB) communication channel measurements. The first method is the Through, Open, Short

    and Match (TOSM) calibration technique. The second method is Through, Reflection and Load (TRL)

    calibration technique. Presented experiment results show that the TRL calibration process is more precise for

    calibration of coaxial cables and the UWB channel as clearly seen by increased magnitudes of the channel

    transfer function. It is also shown that the proposed TRL technique leads to an improved larger measured RMS

    value and that the measured magnitude transfer function of the wireless channel is increased by an absolute

    value of approximately 5 dB after calibration compared with results achieved when TOSM technique is used. In

    the paper, it is also shown that the time delay associated with test equipment of the UWB channel measurement

    can be equally well removed by using either the TRL or TOSM calibration techniques.
