Khan, Faisal Habib | Quantifying device degradation in live power converters using SSTDR assisted impedance Matrix | A noninterfering measurement technique designed around spread spectrum time domain reflectometry (SSTDR) has been proposed in this paper to identify the level of aging associated with power semiconductor switches inside a live converter circuit. Power MOSFETs are one of the most age-sensitive compon... | 2014-01-01 | |

Khan, Faisal Habib | Reliability analysis and performance degradation of a boost converter | In general, power converters are operated in closed-loop systems, and any characteristic variations in one component will simultaneously alter the operating point of other components, resulting in a shift in overall reliability profile. This interdependence makes the reliability of a converter a com... | 2014-01-01 | |

Mathews, V. John | Blind identification of QAM signals using a likelihood-based algorithm | This paper presents a method for automatically identifying different QAM modulations. This method identifies the modulation type as the hypothesis for which the likelihood function of the amplitudes of the received signal is the maximum. The derivation of the likelihood functions assumes additive wh... | 2013-01-01 | |
