Ergodic capacity and average rate-guaranteed scheduling for wireless multiuser OFDM systems
2008
2008 IEEE International Symposium on Information Theory
The challenging task of scheduling multi-user orthogonal frequency-division multiplexed transmissions amounts to jointly optimum allocation of subcarriers, rate and power resources. The optimization problem for deterministic channels reduces to an integer program known to be exponentially complex. Interestingly, the present paper shows that almost surely optimal allocation is possible at low complexity in the wireless setup, provided that the random fading channel has continuous distribution
