Positioning algorithms for cooperative networks in the presence of an unknown turn-around time
(IEEE, 2011)
This paper addresses the problem of single node positioning in cooperative network using hybrid two-way time-of-arrival and time-difference-of-arrival where, the turn-around time at the target node is unknown. Considering ...
Stochastic signaling under second and fourth moment constraints
(IEEE, 2010)
Stochastic signaling is investigated under second and fourth moment constraints for the detection of scalar-valued binary signals in additive noise channels. Sufficient conditions are derived to determine when the use of ...
Noise-enhanced M-ary hypothesis-testing in the minimax framework
(IEEE, 2009-09)
In this study, the effects of adding independent noise to observations of a suboptimal detector are studied for M-ary hypothesis-testing problems according to the minimax criterion. It is shown that the optimal additional ...
Noise enhanced detection in multiple-access environments
(IEEE, 2009)
Under certain conditions, addition of noise can enhance performance of suboptimal detectors, which is called the stochastic resonance (SR) effect. In this paper, the effects of SR are investigated for conventional detectors ...
Effects of additional independent noise in binary composite hypothesis-testing problems
(IEEE, 2009-09)
Performance of some suboptimal detectors can be improved by adding independent noise to their observations. In this paper, the effects of adding independent noise to observations of a detector are investigated for binary ...
Clutter detection algorithms for airborne pulse-Doppler radar
(IEEE, 2010)
Clutter detection is an important stage of target detection. Clutter may not always appear around zero Doppler frequency when realistic terrain models and moving platforms are considered. Two algorithms developed for clutter ...
Optimal stochastic signal design and detector randomization in the Neyman-Pearson framework
(IEEE, 2012-03)
Power constrained on-off keying communications systems are investigated in the presence of stochastic signaling and detector randomization. The joint optimal design of decision rules, stochastic signals, and detector ...
Stochastic signal design on the downlink of a multiuser communications system
(IEEE, 2012-06)
Stochastic signal design is studied for the downlink of a multiuser communications system. First, a formulation is proposed for the joint design of optimal stochastic signals. Then, an approximate formulation, which can ...
Convexity properties of outage probability under Rayleigh fading
(IEEE, 2012)
In this paper, convexity properties of outage probability are investigated under Rayleigh fading for an average power-constrained communications system that employs maximal-ratio combining (MRC) at the receiver. By studying ...
Successive cancelation approach for doppler frequency estimation in pulse doppler radar systems
(IEEE, 2010)
In this paper, a successive cancelation approach is proposed to estimate Doppler frequencies of targets in pulse Doppler radar systems. This technique utilizes the Doppler domain waveform structure of the received signal ...
