Abstract
In this paper, we propose the occupied bandwidth(OBW) measurement method for effectively measuring the 99 $\%$ OBW at monitoring station. In order to validate the measurement results obtained from the proposed measurement method, the modified adjacent channel power ratio(MACPR) is herein defined as the formula which was suitable for applying to the OBW measurement of 8-VSB DTV signals. It has been found that the MACPR is a good measurement parameter applicable for the proper site selection of monitoring station and the effective OBW measurement of 8-VSB DTV signals should be made for MACPR$\geq$35 dB with 600 measurement trials. The proposed measurement procedure is herein given and proven to effectively be applicable to the OBW measurement of terrestrial 8-VSB DTV signals on the air.
