In this paper we study a transmission power-tune/control problem in the context of 802.11 Wireless Local Area Networks (WLANs) with multiple (and possibly densely deployed) access points (APs). Previous studies on power control tend to focus on one aspect of the control, either its effect on transmission capacity (PHY layer) assuming simultaneous transmissions, or its effect on contention order (MAC...
As good candidates for uplink multiple access scheme in broadband wireless communication systems, orthogonal frequency division multiplexing (OFDM) and single-carrier (SC) with frequency division multiple access (FDMA) have gained enough attention recently. However, the non-linearity of amplifier deteriorates the performances of these two schemes. On the assumption of non-linear amplifier applied,...
