ABSTRAK Spektrum 1087.7-1092.3 MHz telah dialokasikan untuk global flight tracking padaWorld Radiocommunication Conference (WRC-15). ADS-B adalah suatu sistembroadcast pada pesawat terbang yang memberikan informasi mengenai posisipesawat (latitude dan longitude), altitude, velocity, aircraft ID, dan informasilainnya yang didapat dari sistem on-board. Metode implementasi ADS-B padapesawat adalah dengan mengirimkan pesan data yang diformat pada Mode Stransponder melalui frekuensi 1090 MHz. Terdapat kemungkinan untukmemanfaatkan frekuensi 1090 MHz sebagai pembawa transmisi Voice CockpitRecording (VCR) dari pesawat ke satelit. Tesis ini membuat simulasi tentangspeech compresion untuk voice cockpit recording menggunakan Discrete WaveletTransform. Hasil kompresi di transmisikan ke satelit menggunakan frekuensi ADSB.Kualitas suara yang diterimakan pada receiver diuji menggunakan MeanOperation Score. Simulasi menghasilkan bahwa Daubechies12, Coiflet5, Symlet10dan Biorthogonal2.6 mempunyai nilai Ratio Compression and PSNR yang terbaik.Hasil MOS rata-rata menunjukkan bahwa file hasil transmisi memiliki derau dansedikit menggangu. Dari hasil simulasi BER dan pengujian MOS maka kompresidengan mother-wavelet Daubechies12 mempunyai hasil yang terbaik. Disimpulkanbahwa kompresi dengan teknik Discrete Wavelet Transform dapat digunakan untukmengirim voice cockpit recording dengan frekuensi ADS-B ke satelit ABSTRACT Spectrum 1087.7-1092.3 MHz had been allocated to global flight tracking civilaviation. Automatic Dependent Surveillance Broadcast (ADS-B) is an aircrafttechnology to broadcast information such as latitude, longitude, altitude, velocity,and also the aircraft identity to the satellite using mode S transponder with 1090MHz center frequency. There?s an opportunity to utilize 1090 MHz as thetransmission carrier of Voice Cockpit Recording (VCR) from aircraft to satellite.This paper investigates voice cockpit recording simulation using Discrete WaveletTransform based compression technique. The compressed voice was transmitted tothe satellite using ADS-B frequency. The received sound was also tested by MeanOperation Score. The simulation found that Daubechies12, Coiflet5, Symlet10 andBiorthogonal2.6 has the best result of Ratio Compression and PSNR. From theBER simulation result and average MOS results have indicated that Daubechies12has the best results. It concluded that speech compression with Discrete WaveletTransform can be used for sending the voice cockpit recording over ADS-B viasatellite reception. |
