Frequency offset estimation of the linear mixture of two co-frequency 8 phase-shift keying modulated signals

Posted on January 28, 2016 by Matlab-Projects |

A frequency offset estimation (FOE) algorithm based on the maximum-likelihood criterion is proposed for the linear mixture of two 8PSK modulated signals with fixed frame length and frame synchronisation code on the…

Families of multi-dimensional arrays with optimal correlations between all members

Posted on January 28, 2016 by Matlab-Projects |

Families of sequences with low off-peak autocorrelation and low cross-correlation are highly valued in spread-spectrum communication. Digital watermarking has an equal need for diverse families of orthogonal multi-dimensional (nD) arrays, where each…

Kalman filter based motion estimation algorithm using energy model

Posted on January 28, 2016 by Matlab-Projects |

Digital video signal compression is an important requirement for multimedia systems. It can be performed by block-based motion estimation algorithms, which eventuate into acceptable outcomes in both the compression and quality. Already adaptive…

Modified SLM method for reduction of PAPR in OFDM systems using decimal sequences

Posted on January 28, 2016 by Matlab-Projects |

Orthogonal frequency division multiplexing (OFDM) is an attractive current technology to achieve high data rate in wireless communication systems. One of the main drawback associated with the OFDM is high…

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…

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…
