Outline of Final Research Achievements

In this research, we developed platforms for software radio and software audio and carried out evaluation experiments. For software radio, we used GNU Radio, measured communication characteristics by changing transmission power, modulation and error correction, and tried wireless delivery of music, still images and motion pictures as its application. For software audio, we used commercial speakers, microphones and MATLAB, measured communication characteristics, and tried delivery of music and still images modulated over audio signals. Our software audio failed video transmission due to low data rates, but the results were paid attention and accepted by IEEE WCNC 2015 heled in March, 2015.
