We previously proposed a digital pre-distortion technique that has transmitter-built-in satellite transponder characteristics to compensate for channel distortion. This technique improves transmission performance, but it is prerequisite that the satellite transponder characteristics are basically known, and it is important to keep knowing the TWTA characteristics in the satellite transponder after the launching of the satellite as it ages. In this study, we propose a technique for estimating the TWTA characteristics at a receiver when a modulation signal is transmitted. |
