Abstract

Network coding di dalam sistem komunikasi semakin populer dan berkembang dikarenakan kemampuanya dapat mengurangi delay dan meningkatkan throughput. Disaat yang bersamaan, teknik modulasi Orthogonal Frequency Division Multiplexing (OFDM) juga semakin populer dan berkembang. Hadirnya OFDM memiliki keuntungan dalam mengefisiensikan penggunaan spektrum bandwidth dan ketahanan terhadap ISI. Penggabungan kedua teknologi diharapkan mampu menggabungkan keuntungan – keuntungan dari kedua sistem. Pada tugas akhir, penulis membangun sistem komunikasi OFDM dengan skema network coding. Guna memperlihatkan unjuk kerjanya, penulis juga membangun sistem komunikasi OFDM dengan skema direct dan multihop. Selanjutnya parameter yang dianalisa adalah bit error rate, waktu satu siklus transmisi dan uji coba pengiriman citra gambar. Kemudian parameter tersebut dianalisa dan dibandingkan kinerjanya. Hasil dari pengujian menunjukkan skema network coding dan multihop konvensional memperbaiki performa BER rata – rata dari skema direct sebesar 10dB pada nilai 10-3. improvisasi dari waktu satu siklus transmisi rata – rata 27% lebih cepat , perbaikan throughput sebesar ± 28% dan perbaikan PSNR pada pengiriman citra yang dikirim. ================================================================================================================== Network coding in communication systems growing more and more popular due to its ability to reduce delay and improve throughput. At the same time, the modulation technique of Orthogonal Frequency Division Multiplexing (OFDM) is also getting popular and growing. The presence of OFDM has an advantage in the use of spectrum bandwidth efficiently and resistance to ISI. Merging the two technologies is expected to combine the advantages of both systems. In this final project, the authors build OFDM communication systems with network coding scheme. To demonstrate its performance, the authors also construct OFDM communication system with direct and multihop scheme. Parameter measured were the bit error rate, one cycle of transmission and testing of picture image delivery. Then these parameters are analyzed and compared its performance. Results of the testing showed network coding scheme and the conventional multihop improve BER performance - average of the direct scheme by 10dB on the value of 10-3. Improves of average transmission time of one cycle - average 27% faster, Improves 28% of throughput and PSNR improvement in average delivery posted image average by 11 dB.
