In non-orthogonal multiple access (NOMA), signals of different users are independently encoded and modulated, then superposed in the power domain before transmission. The choice a suitable combination allocation factor (PAF) transmit constellations is hence critical to enhance system performance. aim this work develop tool for adaptively selecting PAF an enhanced data rate, given some individual user bit error rate (BER) constraints that need be jointly considered. For purpose, analytical...
The application of non-orthogonal multiple access (NOMA) to multicarrier systems can improve the spectrum efficiency and enable massive connectivity in future mobile systems. Resource allocation NOMA is a non-deterministic polynomial time-hard problem requiring exhaustive search, which has prohibitive computational complexity. Instead, efficient algorithms that provide good trade-off between system performance implementation practicality are needed. In this paper, exact values optimal...
The problem of resource allocation in non-orthogonal multiple access (NOMA) systems is nondeterministic polynomial time (NP)-hard and requires exhaustive search. Hence, fast computationally efficient algorithms that provide a performance close to optimal are needed. In this paper, the divided into sub-problems subcarrier assignment power allocation. users' channel condition relationship derived terms effective system sum-rate, ideal partner search algorithm (IPSA) proposed relationship. IPSA...
Vehicle-to-everything V2X applications usually have strict latency requirements that can be difficult to meet in traditional cloud-centric networks. By pushing resources edge servers located closer the users, end-to-end greatly reduced. Task offloading edge-cloud environments refers optimization of which tasks should offloaded between and cloud. Moreover, use containers virtualize further reduce resource time consumption and, turn, applications. Even though Kubernetes has become de facto...
The application of non-orthogonal multiple access (NOMA) to multicarrier (MC) systems can improve the spectrum efficiency and enable massive connectivity in future mobile communication systems. Resource allocation MC NOMA is a non-deterministic polynomial time (NP)-hard problem with prohibitive computational complexity. Thus, efficient algorithms that provide good trade-off between performance complexity are needed. In this paper, exact values optimal channel gain ratios pair users presented...
The problem of resource allocation in multicarrier non-orthogonal multiple access (NOMA) systems is non-deterministic polynomial time (NP)-hard and requires exhaustive search, which has prohibitive computational complexity. Computationally-efficient algorithms that provide a performance close to optimal are needed. In this paper, the divided into two sub-problems, namely subcarrier assignment power allocation. users' channel condition relationship derived terms effective system sum-rate,...
