This paper presents a new rate adaptive resource allocation technique for multiuser orthogonal frequency division multiplexing (OFDM) systems. We optimize both bit and subcarrier allocation by considering rate maximization and total power constraint satisfaction. We solve them effectively by combining them into a multi-objective optimization problem. We(More)
The idea of using the idle resources of a system for some other useful purpose is not new. seti@home pioneered this concept of “public resource computing” by bringing together millions of users worldwide who were ready to donate their idle CPU cycles to the cause of searching the extra terrestrial intelligence. In this paper, we describe a(More)
