Abstract
ABTRACT This paper addresses Differential Binary Phase Shift Keying (DBPSK) modulation implemented on SDR platform for the development of digital data communications based on SDR. DBPSK modulation performance perceived at Packet Error Rate (PER) is evaluated in terms of Eb/No or S/N ratio, carrier frequency, bit rate, gain, roll-off factor of root Nyquist filter or root raised cosine filter, and of size of payload from delivered data. Based on this results, the smallest PER could be obtained by setting Eb/No value which is greater than 13 dB, carrier frequency of at least 0,3 MHz, optimum bit rate of 256 kbps, optimum range payload size of 2000 up to 4000 bytes, and roll-off factor of Nyquist or root-raised cosine filter of 0.1 < alfa < 0.9. INTISARI Makalah ini membahas pengujian unjuk-kerja modulasi Differential Binary Phase Shift Keying (DBPSK) yang diimplementasikan pada platform Software-Defined Radio (SDR) dalam rangka pengembangan sistem komunikasi digital berbasis SDR. Unjuk-kerja modulasi DBPSK diamati dalam bentuk Packet Error Rate (PER) dengan berbagai variasi nilai perbandingan Eb/No atau S/N, frekuensi pembawa, bit rate, gain, roll-off factor pada filter root Nyquist atau filter root raised cosine, dan ukuran payload data yang dikirimkan. Berdasarkan hasil penelitian ini, nilai PER terendah dapat diperoleh dengan mengatur nilai Eb/No lebih besar dari 13 dB, frekuensi pembawa minimal 0,3 MHz, bit rate optimum 256 kbps, ukuran payload optimum berkisar 2000 sampai dengan 4000 bytes, dan nilai roll-off factor pada filter Nyquist atau filter root-raised cosine adalah 0.1 < alfa < 0.9.
