Abstract

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.

Summary

LDPC Encoder

Blok Interleaver ver bit informasi yang dikirim dari outer code (BCH) akan ada 2 bit cek paritas yang ditambahkan dalam LDPC encoder, terlihat dari nilai matriks yang dihasilkan, keluaran BCH adalah matriks [32204x1] sedangkan. QPSK hasil keluaran dari LDPC encoder adalah [64800x1]. Modulator Kemudian hasil keluaran ini akan masuk kedalam blok interleaver, blok ini berfungsi untuk menciptakan baris

QPSK dimana didalam satu simbol akan terdapat
