This proposal aims to offer a solution to the third generation system s constraint of allocating only adjacent subcarriers by providing an optimal resource allotment under a fairness scheme. A multiuser mobile environment following the third generation partnership project TS 45.005v9.3.0 25.943v9.0.0 was also implemented for evaluating the scheduler s performance. From the results it was possible to examine the channel frequency response for all users four user equipments along the whole bandwidth to visualize the dynamic resource allocation for each of the 10 000 channel realizations considered to generate the statistical distribution and cumulative distribution functions of the obtained global costs as well as to evaluate the system s performance once the proposed algorithm was embedded. Comparing and emphasizing the benefits of utilizing the proposed dynamic allotment instead of the classic static-scheduling and other existent methods.

Introduction The third Generation Partnership Project 3GPP has agreed to utilize the single carrier frequency division multiple access .
