Kertas kerja ini mencadangkan seni bina pembatal gangguan untuk komunikasi satelit dengan transmisi super-pose, yang boleh digunakan bukan sahaja untuk QPSK tetapi juga untuk penghantaran 16QAM untuk mendapatkan kapasiti satelit yang lebih tinggi. Kami melaksanakannya sebagai prototaip berasaskan FPGA dan mengesahkan prestasinya. Kami mencadangkan di sini untuk menggunakan kaedah baharu untuk mengukur kelewatan perjalanan pergi balik satelit menggunakan penapis padanan lanjutan (EMF), yang boleh berfungsi dalam keadaan C/N rendah seperti 0 dB dan ke bawah. Memandangkan prestasi ini, pembatalan kami boleh berfungsi dalam rangkaian di mana pautan ke hadapan dan belakang mempunyai tahap kuasa yang sama. Keputusan ujian makmal untuk QPSK menunjukkan bahawa gangguan boleh ditindas oleh kira-kira 30 dB dan bahawa degradasi BER disebabkan oleh pembatalan adalah cukup kecil untuk operasi.

Abstract: This paper proposes an architecture of an interference canceller for satellite communications with super-posed transmission, which is applicable not only to QPSK but also to 16QAM transmission to get higher satellite capacity. We implement it as an FPGA-based prototype and verify its performance. We propose here to use a new method to measure the satellite round-trip delay using an extended matched filter (EMF), which can work in low C/N conditions such as 0 dB and under. Given this performance, our canceller can work in a network in which forward and reverse links have the same power level. The results of the laboratory tests for QPSK show that interference can be suppressed by about 30 dB and that the BER degradation due to the canceller was small enough for operation.
