Enabling relay selection in non-orthogonal multiple access networks: direct and relaying mode
In this paper, we consider downlink non-orthogonal multiple access
(NOMA) in which the relay selection (RS) scheme is enabled for cooperative networks. In particular, we investigate impact of the number of relays on system performance in term of…

Empirical measurement for path loss characteristics at multiple frequency bands from 2.2 to 14.6 GHz in chamber room
Free space path loss (FSPL) is the loss of electromagnetic signal strength.
This loss is caused by the line-of-sight path through free space. Even in a
line of sight (LoS) indoor single layer, as the distance increases, the path loss in the 1 GHz…
