The document discusses software defined radio (SDR) technology using quadrature amplitude modulation (QAM). It begins with an introduction to SDR and QAM. It then covers QAM modulation techniques in more detail and discusses their advantages and disadvantages. The document outlines the research methods used and presents results showing the performance of different QAM modulation schemes through graphs of Eb/No versus bit error rate and indoor and outdoor testing. It concludes with thanking the reader and asking if there are any questions.
