Abstract
This paper addresses the problem of resource allocation in a multiservice optical network based on an
overlapped code-division-multiple-access system. A joint transmission power and overlapping coefficient
(transmission rate) allocation strategy is provided via the solution of a constrained convex quadratic optimization
problem. The solution of this problem maximizes the aggregate throughput subject to peak laser transmission power
constraints. The optimization problem is solved in a closed form, and the resource allocation strategy is simple to
implement in an optical network. Simulation results are presented, showing a total agreement between the derived
analytical solution and the one obtained using a numerical search method. In addition, analytical and numerical
results show that the proposed resource allocation strategy can offer substantial improvement in the system
throughput.
