Abstract EN
We consider the problem of joint resource allocation and admission control in a secondary code-division network coexisting with a narrowband primary system.
Our objective is to find the maximum number of admitted secondary links and then find the optimal transmitting powers and code sequences of those secondary links such that the total energy consumption of the secondary network is minimized subject to the conditions that primary interference temperature constraints, secondary signal-to-interference-plus-noise ratio (SINR) constraints and secondary peak power constraints are all satisfied.
This is an NP-hard optimization problem which motivates the development of suboptimal algorithms.
We propose a novel iterative algorithm to solve this problem in a computationally efficient manner.
Numerical results demonstrate that the proposed algorithm provides excellent solutions that result in high energy efficiency and large admitted percentage of secondary links.
