This paper addresses the maximum achievable rate for amplify-and-forward (AF) one-way relay channel (OWRC) and two-way relay channel (TWRC) with a total transmit power constraint. The achievable rate is maximized for both channels where the optimal power allocation is applied over all the nodes and the closed-form expressions for the maximum achievable rate(More)
OBJECTIVE To determine the effect of internal ribosome entry site (IRES)specific inhibitor RNA (IRNA) on viral gene expression mediated by HCV 5' noncoding region (NCR) in human hepatic carcinoma cell line. METHODS Cotransfection of pCMVNCRluc containing 5'NCR-luc fusion genes and eukaryotic vectors of IRNA into human hepatic carcinoma cells (HHCC) was(More)
—This letter studies the outage performance of cooperative non-orthogonal multiple access (NOMA) network with the help of an amplify-and-forward relay. An accurate closed-form approximation for the exact outage probability is derived. Based on this, the asymptotic outage probability is investigated, which shows that cooperative NOMA achieves the same(More)
In this paper, we study the uplink of a relay-assisted multiuser massive MIMO system. The relay station (RS) equipped with M<sub>1</sub> antennas processes the received signal from K single-antenna users, using maximum ratio combining (MRC)/zero-forcing (ZF) detection, and then forwards the post-processed signal to the base station (BS) with M<sub>2</sub>(More)
