Abstract

The invention discloses a quick algorithm for joint resource allocation in a heterogeneous wireless network parallel multi-access system. When the joint resource allocation is performed in the heterogeneous wireless network parallel multi-access system, the bandwidth and power allocations are separated and the resource allocation is performed in turn, wherein the bandwidth allocation under the condition of equal power allocation is firstly performed; in the bandwidth allocation process, the advantage of high convergence rate of a Newton method is fully taken, thereby reducing the arithmetic complexity and increasing the arithmetic rate; and then the power allocation is performed; and if a power allocation result is a negative value, the bandwidth and the power are allocated again, thereby more fully utilizing the bandwidth and power resources as well as increasing the arithmetic efficiency and rate. By utilizing the algorithm to perform the joint resource allocation in the heterogeneous wireless network parallel multi-access system, the purpose of approaching the acquired resource allocation optimal solution to the theoretical optimum solution is achieved. The algorithm can be used for quickly allocating the joint resource in the heterogeneous wireless network parallel multi-access system.
