In this paper fading multiple-antenna (MIMO) wiretap channels are investigated under short term power constraints. The secret diversity- multiplexing tradeoff (DMT) is calculated analytically, when the destination and the eavesdropper have receiver side channel state information (CSI) and the source has transmitter side CSI (CSIT). It is shown that the eavesdropper steals transmitter antennas and the secret DMT depends on the effective number of antennas left. This is in contrast to the no CSIT case, where the eavesdropper effectively steals both transmit and receive antennas. A zero-forcing type scheme is shown to achieve the secret DMT when CSIT is available. © 2010 IEEE.

Diversity-Multiplexing Tradeoff for the Multiple-Antenna Wire-tap Channel Yüksel Turgut, Ayşe Melda; Erkip, Elza (2011-03-01) In this paper the fading multiple antenna (MIMO) wire-tap channel is investigated under short term power constraints. The secret diversity gain and the secret multiplexing gain are defined. Using these definitions, the secret diversity-multiplexing tradeoff (DMT) is calculated analytically for no transmitter side channel state information (CSI) and for full CSI. When there is no CSI at the transmitter, under the assumption of Gaussian codebooks, it is shown that the eavesdropper steals both transmitter and ...
Diversity-multiplexing tradeoff for the multiple-antenna wire-tap channel Yüksel Turgut, Ayşe Melda; Erkip, Elza (2008-01-01) In this paper the fading multiple antenna (MIMO) wire-tap channel is investigated. The secret diversity gain and the secret multiplexing gain are defined. Using these definitions, the secret diversity-multiplexing tradeoff (DMT) is calculated analytically when the source node does not have transmitter side channel state information (CSI). It is shown that the wire-tapper steals degrees of freedom from the source-destination channel, and the secret DMT depends on the remaining degrees of freedom. When CSI is...
Dynamic analysis of CMUTs in different regimes of operation Bayram, Barış; Ergun, AS; Yaralioglu, GG; Khuri-Yakub, BT (2003-01-01) This paper reports on dynamic analysis of an immersed single capacitive micromachined ultrasonic transducer (CMUT) cell transmitting. A water loaded 24 mum circular silicon membrane of a transducer was modeled. The calculated collapse and snapback voltages were 80 V and 50 V, respectively. The resonance frequency, output pressure and nonlinearity of the CMUT in three regimes of operation were determined. These regimes were: a) the conventional regime in which the membrane does not make contact with the subs...
Total outage capacity of randomly-spread coded-CDMA with linear multiuser receivers over multipath fading channels Ertug, O; Sayrac, B; Baykal, Buyurman; Yucel, MD (2003-07-03) We address in this paper the derivation and analysis of the outage spectral efficiencies achievable with linear multiuser receivers over randomly-spread multipath fading time-varying coded-CDMA channels. The basis of the derivations is the use of non-asymptotic average eigenvalue densities of random cross-correlation matrices. The analysis give important clues on the achievable capacity with linear multiuser receivers under non-ergodic transmission situations.
Optimal Power Allocation for Average Detection Probability Criterion Over Flat Fading Channels Sarıtaş, Serkan; Sezer, Ahmet Dundar; Gezici, Sinan; Yuksel, Serdar (2017-03-01) In this paper, the problem of optimal power allocation over flat fading additive white Gaussian noise channels is considered for maximizing the average detection probability of a signal emitted from a power constrained transmitter in the Neyman-Pearson framework. It is assumed that the transmitter can perform power adaptation under peak and average power constraints based on the channel state information fed back by the receiver. Using results from measure theory and convex analysis, it is shown that this o...
