Wideband Man-Made Radio Noise Measurements in the VHF and Low UHF Bands
Abstract: Man-made radio noise measurements were conducted in a 1.16-MHz bandwidth at 112.5, 221.5, and 401 MHz at two residential and two business locations in the Boulder/Denver, Colorado, area. The measurement frequencies and bandwidth were selected using the results of a spectrum survey performed over the 104– 1060-MHz frequency range. The noise measurement data were collected as a complex baseband noise data record (consisting of six million in-phase (I) and quadrature-phase (Q) samples) every 10 minutes over a 24-hour period for each frequency and location.
