The combination of radio-frequency (RF) communication and underwater optical wireless
communication (UOWC) plays a vital role in the underwater Internet of things (UIoT). This correspondence
proposes a dual-hop hybrid satellite underwater system that exploits non-orthogonal multiple access
(NOMA) as a spectrum-efficient access technique. The RF lin...
This work investigates the performance of a downlink non-orthogonal multiple access (NOMA) based coordinated low-earth orbit (LEO) satellite system. Two LEO satellites are assumed to coordinate their transmissions to serve three users simultaneously using NOMA protocol, where only one user lies in the intersection of the footprints of the two satel...
p>This paper investigates the performance of non-orthogonal multiple access (NOMA) based hybrid satellite-unmanned aerial vehicle (UAV) systems, where a low Earth orbit (LEO) satellite communicates with the ground users via a decode and forward (DF) UAV relay. We investigate a two NOMA users system, where a far user (FU) and a near user (NU) are se...

The quality of speech is essential in communication systems. Enhanced Voice Services (EVS) is one of the speech Coders that standardized by the 3GPP for LTE. EVS supports audio bandwidth, offers high quality for mixed content (i.e. speech and music). Many coders that depend on the concept of ACELP may be affected by the change in the spoken languag...
