Efficient Allocation for Downlink Multi-Channel NOMA Systems Considering Complex Constraints

Efficient Allocation for Downlink Multi-Channel NOMA Systems Considering Complex Constraints

To enable an efficient dynamic power and channel allocation (DPCA) for users in the downlink multi-channel non-orthogonal multiple access (MC-NOMA) systems, this paper regards the optimization as the combinatorial problem, and proposes three heuristic solutions, i.e., stochastic algorithm, two-stage...
