Antenna subset selection at multi-antenna relay with adaptive modulation
( John Wiley & Sons, Ltd. , 2013 , Article)In this paper, we proposed several antenna selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes were based on dual-hop relaying where a relay with multiple-antenna capabilities ... -
Comments on: "Fault detection for continuous-time switched systems under asynchronous switching"
( John Wiley & Sons, Ltd. , 2015 , Article)In this note, a defect occurred in Theorem 1 in the study Du et al. (Int. J. Robust Nonlinear Control 2013; doi: 10.1002/rnc.2961) is addressed. Additionally, the correction of the theorem is presented. -
High gain observer for a three-cell chopper: Design and experimental results
( John Wiley & Sons, Ltd. , 2014 , Article)As capacitor voltages are necessary for the three-cell DC�DC chopper control, the estimation of such voltages by an observer is attractive solution in terms of cost. However, due to the hybrid behavior of this structure, ... -
Multi-component instantaneous frequency estimation using locally adaptive directional time frequency distributions
( John Wiley & Sons, Ltd. , 2015 , Article)This paper presents a locally adaptive time-frequency (t,f) method for estimating the instantaneous frequency (IF) of multi-component signals. A high-resolution adaptive directional time-frequency distribution (ADTFD) is ... -
Relay selection in underlay cognitive networks with fixed transmission power nodes
( John Wiley & Sons, Ltd. , 2013 , Article)Underlay cognitive networks operate simultaneously with primary networks satisfying stringent interference constraints, which reduces their transmission power and coverage area. To reach remote destinations, secondary ...
