Abstract

In a wireless OFDM communication system multiple players share the same spectrum while experiencing different channel realizations. Allocation algorithms exploit this feature and optimize the allocation of frequency bins according to various optimization criteria (e.g., weighted Max-Min, Nash Bargaining Solution (NBS), etc). These allocations do not allow players to transmit on the same frequency bin simultaneously. Thus, the communication channel is not fully utilized when the mutual interferences are weak. Here we propose a more general allocation scheme, called Partial Orthogonal Allocation (POA), where players can transmit simultaneously on some of the frequency bins, and maintain orthogonality of transmission on the other frequency bins. For this schema, the Nash Bargaining Solution is proposed and analyzed.
