METHODS AND DEVICE FOR MEASURING THE INTERFERENCE LEVEL OF VSAT TDMA TERMINALS CAUSING CROSS-POLAR AND/OR ADJACENT SATELLITE INTERFERENCE IN A COMMUNICATION LINK

摘要

It is described a method for measuring the interference level of VSAT TDMA terminals causing cross-polar and/or adjacent satellite interference in a communication link, the terminals (13) communicating with a hub station (14) via a first satellite (11). The method includes the steps of:receiving a burst time plan from the hub station (14) or establishing a burst time plan by receiving and decoding signals transmitted from the terminals (13) to the hub station (14),selecting a particular terminal occurring in the burst time plan,receiving signals transmitted from said selected terminal to the hub station,receiving signals in said interfered communication link,correlating the waveform of the signals transmitted from said selected terminal to the hub station with the waveform of signals received in said communication link to detect any interference that may be present in the communication link.
