Performance enhancement of cognitive relay networks using regression functions
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In a spectrum sharing relay-aided secondary network, the design objective shifts from minimizing the violation of the primary system constraints when using the outdated channel state information (CSI), to making the best ...
A dual three-phase induction machine based flywheel storage system driven by modular multilevel converters for fault ride through in HVDC systems
(
IEEE Computer Society
, 2016 , Conference Paper)
One of the main challenges of voltage source converter based high voltage direct current (VSC-HVDC) transmission systems is the AC faults at the grid side. This work introduces the integration of multiphase induction machine ...
A wireless oxygen saturation and heart rate monitoring and alarming system based on the Qatar early warning scoring system
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Monitoring vital signs and alarming healthcare emergency response units whenever measurements are outside the normal range could be life-saving for high-risk patients who are living alone or sleeping. This paper presents ...
A Novel method for online correction of amplitude and phase imbalances in sinusoidal encoders signals
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Resolvers and other sinusoidal transducers are angular position and speed sensors that produce supposedly perfect sine and cosine signals in which the angular position is encoded. Suitable converters are normally used to ...

, 2016 , Conference Paper)
In this paper, we address the problem of sparse signal recovery, from multi-bit scalar quantized compressed sensing measurements, where the saturation issue is taken into account. We propose a convex optimization approach, ...
Optimal power allocation in dispersed cognitive radio systems with carrier aggregation
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, we investigate the optimal power allocation problem in dispersed cognitive radios with carrier aggregation. To this end, we model the carrier aggregation using an i - th frequency diversity policy, wherein ...
A Matlab/Simulink model for capacitor voltages balancing in modular multilevel converters
(
