Abstract

The development of intelligent resource management algorithms has been recently identified as a key technology for exploiting potential system diversity and improving power-spectral efficiency in wireless communication systems, as well as high-performance physical-layer techniques to provide high throughput, efficient resource use, and aggressive multiple access. In this paper, we propose an adaptive subcarrier allocation algorithm for uplink in multicell point of view using subcarrier sharing. The objective of this paper is to: 1) exploit the inherent system diversities in the frequency, space, and user domains; 2) minimize the overall transmit power; and 3) improve the fairness among users in power aspect. Numerical results shows that tremendous power gain and improvement of the fairness among users is achieved, compared with inherent system. copyright
