Abstract

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.

Abstract

This paper addresses decomposition of the tasks of Software-Defined Radio (SDR) computation by taking Gaussian Minimum Shift Keying (GMSK) as a case study. The aim of this research was to produce a task graph of the SDR that was needed in scheduling of distributed computing with task parallelism using genetics algorithm. Based on the tasks decomposition and the evaluation of execution time of each task, we obtained a task graph of SDR computation. We conclude that there are eleven tasks for the modulator and fifteen for the demodulator.
