Four-way TOA and software-based trilateration of IEEE 802.11 devices
—In this paper we present an algorithm that measures the round trip times of IEEE 802.11 MAC packets in order to trilaterate WLAN nodes. We show that if we use packet sequences (...

Multiuser diversity in channels with limited scatterers
—Multiuser diversity scheduling is studied in a single cell system with a limited scatterers channel. The scheduler implements the proportional fairness algorithm with infinite ...

QoE estimation from MAC-level QoS in audio-video transmission with IEEE 802.11e EDCA
— This paper estimates Quality of Experience (QoE), i.e., user–level QoS from MAC–level QoS for audio–video transmission over an IEEE 802.11e EDCA wireless LAN. The MAC– ...

Signal space diversity for spatial multiplexing
— When channel state information is available at the transmitter, we can diagonalize a MIMO channel with SVD transceivers. However, outage of the weaker eigenchannels limits the ...
