This letter considers a code design for an asymmetric Slepian-Wolf multiple-access relay channel, in which the users and relay have different channel conditions. In this case, the conventional parity approach distributed source coding is no longer applicable. Hence, a new distributed joint source-channel superposition coding (DJSC-SC) is proposed. The proposed DJSC-SC matches the asymmetric channels,...
In this paper, we consider a small cognitive wireless network operator (SCWNO) that provides machine-to-machine (M2M) communications by utilizing TV white spaces (TVWS) and lease high priority channels (HPC) at a cost to achieve better quality-of-service (QoS). We study the economic viability of SCWNO by considering the cost of leasing HPC, delay in data transmission, and quality of data. When the...
Home automation systems represent the front-end of smart grids, where the energy monitoring and control operations are enabled through smart devices installed in households and residential buildings. There are many home automation technologies available in the market, and the users are left to select their choice of best technology. Proper guidelines to their selection currently remain low. Therefore,...
In this paper, we consider a K-cell multi-user interference network, where S single-antenna users are selected within each cell to carry out the uplink transmission with their M-antenna home base station, where 2 ≤ S ≤ M < KS. For the considered scenario, a novel intra-cell performance aware opportunistic interference alignment (OIA) scheme is proposed to mitigate the inter-cell interference while...
