We study the secrecy capacity of the frequency-selective wiretap channel. Assuming that a guard interval of L symbols is inserted to avoid the inter-block interference and these s...
—We extend the existing network utility maximization (NUM) framework for wired networks to wireless sensor networks by formulating it in order to take into account interference a...

—Multi-cell Cooperative Processing (MCP) has been recognised as an efficient technique for increasing spectral efficiency of future cellular systems. However the provided bene...
Abstract-SC-FDMA (Single-Carrier Frequency Division Multiple Access) is employed in tbe 3GPP LTE (Long-Term Evolution) standard as tbe uplink transmission scbeme. Tbe SC-FDMA signa...
—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 scheduling is studied in a single cell system with a limited scatterers channel. The scheduler implements the proportional fairness algorithm with infinite ...
— 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– ...
— 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 ...
