Non-orthogonal multiple access (NOMA), in particular pattern division (PDMA), has been recently considered as the critical technologies deployed for 5G applications. However, optimizing power allocation (PA) at base station (BS) to increase sum throughput of downlink (DL) PDMA system still remains a challenge. Although this problem explored some extent by assuming that BS can obtain perfect cha...

Abstract This paper addresses in-schedule dependent task allocation problems for multi-robot systems. One of the main issues with those is inherent NP-hardness combinatorial optimisation. To handle this issue, develops a decentralised algorithm by leveraging submodularity concept and sampling process sets. Our theoretical analysis reveals that proposed can provide an approximation guarantee 1/2...

Optimal power allocation for secure estimation of multiple deterministic parameters is investigated under a total constraint. The goal to minimize the Cramer-Rao lower bound (CRLB) at an intended receiver while keeping errors eavesdropper above specified target levels. To that end, optimization problem formulated by considering measurement models involving linear transformation parameter vector...
