Principles of time-frequency feature extraction for change detection in non-stationary signals: Applications to newborn EEG abnormality detection
( Elsevier Ltd , 2015 , Article)This paper considers the general problem of detecting change in non-stationary signals using features observed in the time-frequency (t,f) domain, obtained using a class of quadratic time-frequency distributions (QTFDs). ... -
Prior zero forcing for cognitive relaying
( IEEE , 2013 , Article)Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a ... -
Priority-based scheduling for limited energy cognitive relaying
( IEEE , 2010 , Conference Paper)We study the problem of cognitive relaying with limited-energy constraint in opportunistic spectrum access cognitive networks. Under this network setting, the cognitive user increases the spectrum availability for its own ... -
Priority-based zero-forcing in spectrum sharing cognitive systems
( IEEE , 2013 , Article)We consider a spectrum sharing scenario between cognitive radio (CR) users and a licensed primary user (PU), in which the PU is not able to successfully transmit data to its destined receiver. The cognitive base station ... -
