Abstract	Two-way (on-frequency) relaying using simple amplify-and-forward processing at the satellite is an emerging technology that allows doubling of system spectral efficiency for certain networking applications. However, the satellite channel is non-linear and compensation for the self-interfering signal is more difficult than on linear channels, especially when memory effects are recognised. In this paper, we model two-user, asynchronous, bidirectional relaying for uncoded transmission, and proposed a bidirectional satellite communication algorithm under same frequency transmission. First, we employ a table addressed by side-information and the symbol to be detected to model the action of the channel. Then, we employ a linear adaptive canceler followed by a smaller table lookup process to cancel the self-interference and to make decisions. In the simulation part, we focus in the results section is upon 16-amplitude phase shift keying (APSK), widely employed in the DVB-S2 standard for bandwidth-efficient operation. Compared with the existing bidirectional satellite communication algorithm, our proposed algorithm have the far less complexity and training time at the similar performance.
