“…Penelitian yang hampir sama dilakukan oleh G. Gardikis dkk [17] melakukan penambahan Adaptive Coding Modulation pada sistem DVB-S2 dengan membandingkan hasil kinerjanya di dua tempat yang berbeda yaitu Yunani dan Indonesia, hasil kinerja antara dua tempat yang berbeda tergantung curah hujan dimasing-masing area. T. Olshevska dkk [18] melakukan penelitian yang sama dengan menambahkan ACM di DVB-S2 dengan menggunakan modulasi QPSK didapatkan ada penambahan efektivitas kapasitas saluran. H. Kwon dkk [19] melakukan penelitian dengan mendesain dan mengevaluasi kinerja sistem DVB-S2 dengan menambahkan sinyal FTN, didapatkan efektivitas terhadap percepatan pengiriman simbol yang jauh lebih baik.…”

The development of digital video broadcasting is still continue recently and was done by many parties. One of the project regarding this research was DVB project. There was three areas in digital video broadcasting. One of them was Digital Video Broadcasting Satellite Second Generation (DVB-S2). The development of this project is not focus only in video broadcasting but also focus in applications and mutlimedia services. The objective of this research was to implement raised cosine filter in DVB-S2 using matlab simulink in order to optimize SNR and BER value. Parameters used in this project was QPSK mode and LDPC with 50 iteration. Those parameters was chosen to maintain originality of data that sent in noisy channel. The result showed that by implementing raised cosine filter could optimized BER value of the system. The higher SNR value would give the lower BER value. In static video, the best SNR value when using a filter is 0.9 dB with a BER value of 0.000004810 while for dynamic video the SNR is 0.9 with a BER value of 0.00001030.

“…The VCM system given by DVB‐S2 standard 10 and Consultative Committee for Space Data Systems (CCSDS) blue book 11 has the ability to change the coding mode, modulation mode, and bit rate and can dynamically vary the link parameters according to the transmission distance. On the premise of the required link reliability, VCM system can improve the transmission efficiency by more than 30% compared with Constant Coding and Modulation (CCM) system according to DVB‐S standard 12 . High‐order MAPSK modulation and BCH‐LDPC coding technology used in DVB‐S2 standard play a fundamental role in VCM system.…”

As LEO (Low Earth Orbit) high-resolution Earth observation satellite needs to transmit a large amount of remote sensing data from the satellite to the ground station, higher downlink capacity still poses a severe challenge to LEO. Therefore, variable coding and modulation (VCM) has become an important scheme to optimize the performance of satellite downlink. In this paper, the downlink VCM system of China Earth observation satellite is studied for the first time. By evaluating the free space loss of the satellite downlink path, a VCM-based satellite downlink system is designed, and a DVB-S2 BCH-LDPC encoded variable bit rate high-order MAPSK modulator is implemented. The maximum channel bit rate can reach 3.5 Gbps. Then, the experimental results of Gaofen-7 satellite, which was launched in November 2019, are carried out which showed that our design method effectively meets the design requirements, and the performance is verified.
