Abstract(in English) The interference canceller for satellite carrier super-positioning multi-level PSK transmission has been designed and developed by us. The test has been conducted by us for the verification of the canceller performance in both linear and nonlinear channels for QPSK and 8PSK. The results show that though it performs very well in the linear transmission path, the performances is degraded in the nonlinear channel. The trends are more true as we choose multi-level modulation scheme. This paper shows the canceller algorithms developed by us and reports the experimental test results of it in the very near environment of the actual satellite transmission path. The results show that nonlinear compensation scheme is inevitably required to improve the performance in the nonlinear channel.
