Advanced digital nonlinear distortion compensation

Posted on January 28, 2016 by Matlab-Projects |

We review the recent progresses on the nonlinear perturbation pre-distortion including the modified nonlinear model for performance improvement and nonlinear terms combination for complexity reduction. With Nyquist nonlinear model, the…

Design and development of a smart weighing scale for beehive monitoring

Posted on January 28, 2016 by Matlab-Projects |

In recent years monitoring of beehives through technology has become increasingly frequent in research and industry. This is due to a decline in beekeeping, and stagnant honey bee populations across…

Real time digital signal strength tracking for RF source location

Posted on January 28, 2016 by Matlab-Projects |

A Direction Finding (DF) system is implemented and measured for the 915MHz ISM band. This system covers frequencies up to 1.5GHz with an instantaneous bandwidth of 1.5GHz. It is capable…

An Interoperable System for Automated Diagnosis of Cardiac Abnormalities from Electrocardiogram Data

Posted on January 28, 2016 by Matlab-Projects |

Electrocardiogram (ECG) data are stored and analyzed in different formats, devices, and computer platforms. As a result, ECG data from different monitoring devices cannot be displayed unless the user has…

Iterative Condition Monitoring and Fault Diagnosis Scheme of Electric Motor for Harsh Industrial Application

Posted on January 28, 2016 by Matlab-Projects |

This paper presents a robust diagnosis technique by iteratively analyzing the pattern of multiple fault signatures in a motor current signal. It is mathematically and experimentally proved that the proposed diagnosis…

A new method of fuzzy logic-based steganography for the security of medical images

Posted on January 28, 2016 by Matlab-Projects |

Dicom (Digital Imaging and Communications in Medicine) files stores the personal data of patients in file headers. The personal data of patients can be obtained illegally while archiving and transmitting Dicom…
