This paper considers a cooperative multiple access (CMA) scheme where two full-duplex sources simultaneously send their own messages to common destination. As part of cooperation, each the also receives and relays message from other source. develops algorithms for computing optimal power allocation achieve maximal network throughput subject residual self-interference (RSI) at non-ideal sources....

Researchers for the third-generation partnership project (3GPP) have been exploring — as a cost-effective alternative to wired backhaul integrated access and (IAB) frameworks 5G new radio (NR). A promising solution this framework is integration of full duplex (FD) technologies enhance spectral efficiency efficiently utilize network resources. This approach, which we refer FD IAB, involves signi...

This paper investigates the downlink transmission of reconfigurable intelligent surface (RIS)-aided cooperative non-orthogonal-multiple-access (C-NOMA), where both half-duplex (HD) and full-duplex (FD) relaying modes are considered. The system model consists one base station (BS), two users RIS. goal is to minimize total transmit power at BS user-cooperating relay for each mode by jointly optim...

tehran shomal highway passes through alborz mountains with a tunnel length of 6400 meters. there are two main tunnels. a full three-dimensional (3d) numerical analysis coupled with elasto-plastic material models was conducted on the inclined access tunnel. bending moment, axial force and the lining displacements due to the internal forces applied on the shotcrete lining are calculated. axial fo...

talented individuals, who are bleeding from the nose, usually do not go to the doctor, except in case of sever and unusual bleeding. because traditional method of treatment is not effective in nasopharanx bleeding, so malcolm harvey explain brighton epistaxis balloon as a new method  for controlling nasopharanx bleeding through the paper. epistaxia usually happen in the anterior part of the nas...
