Abstract
We conduct field measurements to assess the effectiveness of the spectrum sharing method using adaptive transmit power control [2]. This investigation assumes a fixed satellite service as the victim and an IMT-Advanced system as the interferer. We evaluate the capacities achieved by adaptive transmit power control in a comparison with fixed-level transmit power control. The results show that adaptive transmit power control attains higher capacities, especially in severe sharing conditions such as the victim receiver operates near a interfering transmitter. We also discuss the impact of introducing interference criteria based on desired signal level at the victim receiver instead of the long-standing noise-based criteria.
