What is NOMA in communication

Non-orthogonal multiple access (NOMA) has been conceived as a breakthrough tech- nology for fifth generation (5G) wireless networks -. The main themes of 5G networks, namely, reduced latency, high connectivity, and ultra-fast speeds are being attributed to devising systems working on the principles of NOMA The key feature of NOMA is to exploit the difference between users' channel conditions In scenarios with single-antenna nodes, channels are scalar and it is easy to order the users based their channel conditions In MIMO, channels are in form of matrices/vectors, which makes difficult to order user NOMA exploits superposition coding at the transmitter and successive interference cancellation (SIC) at the receiver, thus multiplexing users in the power domain. As shown in Fig. 1, the base station (BS) sends the superposed signals to two users, where User 1 has higher channel gain than User 2 We know that NOMA involves successive interference cancellation (SIC), where one user decodes the message of the other user, from the superposition coded received signal, before decoding his own message. Specifically, the near user decodes the information of the far user while performing SIC. There is no escaping this step

Recently, nonorthogonality based system designs are developed to be used in communication networks and have gained significant attention of researchers. Hence, multiple access (MA) techniques can now be fundamentally categorized as orthogonal multiple access (OMA) and nonorthogonal multiple access (NOMA) Non-orthogonal multiple access (NOMA) has been recently recognized as a promising multiple access technique to significantly improve the spectral efficiency of mobile communication networks. In 1G, 2G, and 3G, frequency division multiple access (FDMA), time division multiple access and code division multiple access were introduced, respectively

Gitlin, Life Fellow, IEEE Department of Electrical Engineering, University of South Florida Tampa, Florida 33620, US The key idea of Non Orthogonal Multiple Access (NOMA) is to use the power domain for multiple access (similar to PDMA), unlike its orthogonal counterparts that split the spectrum based on time, frequency, or code. The main issue with this orthogonal multiple access (OMA) technique is that its spectral efficiency is low
