Capacity performance of uplink NOMA system with 2K+1 users over Fisher-Snedecor composite fading channels
In this paper, we study an uplink power-domain non-orthogonal multiple access (PD-NOMA) system, in which 2K+1 users are served. The user clustering process based on High-High/High-Low algorithm precedes the utilization of the data-rate based power allocation algorithm. Channels are characte...

| Summary: | In this paper, we study an uplink power-domain non-orthogonal multiple access
(PD-NOMA) system, in which 2K+1 users are served. The user clustering
process based on High-High/High-Low algorithm precedes the utilization of
the data-rate based power allocation algorithm. Channels are characterized
by Fisher-Snedecor composite fading model interpreted as model with a high
level of generality. The influence of different fading/shadowing channel
conditions, number of users and their positions is portrayed through the
numerical results of data sum rate of the studied PD-NOMA system. |
