Popis: | Non-orthogonal multiple access (NOMA), is one of the fundamental radio access techniques for 5G communication networks that increases the efficiency of the spectrum by multiplexing the users in the power domain to compensate the increasing bandwidth requirements. Although there are plenty of theoretical studies, there is only a couple of experimental studies about NOMA. In this study, a practical downlink NOMA system based on software-based radio (SDR) platform is implemented. Our NOMA system which used in power domain, mainly focuses on superposition coding at transmitter and successive interference cancelation (SIC) at the receiver. The designed NOMA system has been tested over real-time experiments and bit error rate (BER) analyzes have been made. In addition to these, a relay that uses the amplify and forward (AF) method is integrated in the system. |
