For coding with vanishing error probability, the results of Slepian and Wolf (1973) show that time-sharing of the two possible successive encoding scenarios (obtained by interchanging the roles of X and Y) is optimal, in that all achievable rate pairs can be achieved via this strategy. But time-sharing combined with successive encoding may not be an optimal strategy in the case of zero-error coding. The authors construct a simple example for this suboptimality phenomenon.","PeriodicalId":92129,"journal":{"name":"Proceedings.

Achieving multiuser diversity under hard fairness constraints 在硬公平性约束下实现多用户分集

The primary result of this work is that using proper dynamic resource allocation strategies on Rayleigh fading channels can yield a non-negligible power boost which can be as high as 5 or 6 dB, for a moderate number of users employing a joint resource allocation policy. This gain grows logarithmically with the number of users. The main practical issue arising from these results is fairness. Users must wait (or the base station in the case of the broadcast channel) until their channel conditions are favourable enough to transmit. We show in this work that multiuser diversity can still be achieved in a multi-carrier system using simple orthogonal multiplexing even under the constraint that each user receives the same constant bandwidth resource at any time instant.","PeriodicalId":92129,"journal":{"name":"Proceedings.
