resource allocation in scma-based system
نویسندگان
چکیده
in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum rate requirement, total available power in each base station (bs), and scma constraint. to solve the proposed problem an iterative algorithm considering successive convex approximation (sca) is applied. also,convergence of the iterative method is investigated. in the simulation results the effectiveness of proposed resource allocation method are shown.

متن کاملBicriteria Resource Allocation Problem in Pert Networks
We develop a bicriteria model for the resource allocation problem in PERT networks, in which the total direct costs of the project as the first objective, and the mean of project completion time as the second objective are minimized. The activity durations are assumed to be independent random variables with either exponential or Erlang distributions, in which the mean of each activity duration ...
