This paper considers the use of compressive sensing based algorithms for velocity estimation of moving vehicles. The procedure is based on sparse reconstruction algorithms combined with time-frequency analysis applied to video data. This algorithm provides an accurate estimation of object's velocity even in the case of a very reduced number of available video frames. The influence of crucial parameters...
This paper presents the ways to design low budget and high performance laboratory exercises for the purpose of biomedical engineering education. The methodology is based on "use what you have" principle, i.e. compose the BME exercise from the components available on a laboratory desk: inexpensive sensors/actuators, microcontrollers, acquisition interfaces, computers and widely used education...
In this paper we deal with the linear frequency modulated signals and radar signals that are affected by disturbance which is the inevitable phenomenon in everyday communications. The considered cases represent the cases when the signals of interest overlap with other signals or with noise. In order to successfully separate these signals we propose the compressive sensing method, which states that...
Converters synthesis procedures of time-and-frequency signals parameters in a digital code of two variables on the example of the recurrent networks application are developed. Converters structure of time-and-frequency signals parameters in a digital code of two variables on a basis three-layer recurrent network constructed.
Instantaneous frequency estimation of signals in a high noise environment is analyzed in the paper. An algorithm based on Ant colony optimization and Wigner distribution is proposed for solving the considered estimation problem. The proposed approach has been applied and tested on mono-component frequency-modulated signals. Numerical examples are given in order to demonstrate the algorithm's performances...
