This paper introduces some practical issues of the deployment of wireless sensor networks (WSNs) in closed loop digital signal processing (DSP) and control systems that require relatively fast, continuous data flow and real-time operation of the data collecting network, as in the case of traditional systems where sensors are attached by wire. The difficulties of the design of the wireless contr...

The current methods of turfgrass evaluations are often based on human-based assessment methods. However, eliminating subjective errors from such evaluations is often impossible. This research compared the accuracy of human-based and digital image processing-based methods for quality assessment of turfgrasses. Four turfgrass plots were evaluated using the two mentioned methods. In the human-base...

technology that is omnipresent in almost every engineering discipline. Faster additions and multiplications are of extreme importance in DSP for convolution, discrete Fourier transform, digital filters, etc. The core computing process is always a multiplication routine; therefore, DSP engineers are constantly looking for new algorithms and hardware to implement them. Vedic mathematics is the na...

Goal OFDM stands for 'Orthogonal Frequencies Division Multiplexing'. Instead of modulating a single carrier as is the case with FM or AM, the idea to utilize a number of carriers, spread regularly over a frequency band, in such a way that each of them is modulated with just a small portion of the available energy. This can be done in a flexible way so that the available bandwidth is utilized to...

A DSP-based measurement system dedicated to the vibration analysis on rotating machines was designed and realized. Vibration signals are on-line acquired and processed to obtain a continuos monitoring of the machine status. In case of fault, the system is capable of isolating the fault with a high reliability. The paper describes in detail the approach followed to built up fault and unfault mod...

This paper motivates the application of Software defined radio as the enabling technology in the implementation of future wireless terminals for 4G. It outlines the advantages and disadvantages of SDR in terms of Flexibility and reconfigurability versus computational complexity. To mitigate the expected increase in complexity leading to a decrease in energy efficiency, cooperative wireless netw...

We present a programmable continuous-time floating-gate Fourier processor that decomposes the incoming signal into frequency bands by analog bandpass filters, multiplies each channel by a nonvolitile weight, and then recombines the frequency channels. A digital signal processor would take a similar approach of computing a fast Fourier transform (FFT), multiplying the frequency components by a w...
