A further step towards the realization of an innovative instrument for power measurements in DVB-T systems is taken. Past research activity was addressed to the design of the digital processing section, and specifically on the optimization of the measurement algorithm based on sequential Burg estimator. The present work accounts for the digitizing section of the instrument. In particular, bandpass...
The interference effects on voice over Internet protocol (VoIP) applications over wireless local area networks (WLANs) are here dealt with. In particular, attention is paid to the IEEE 802.11 g standard, with Bluetooth signals, additive white Gaussian noise (AWGN) and competitive data traffic acting as interferer. The analysis is conducted experimentally following a cross-layer approach and through...
The performance of video streaming applications over wireless local area network (WLANs), in presence of interference, are here dealt with. In particular, the IEEE 802.11g standard is considered and Bluetooth and WLAN competitive data traffic are analyzed as interferer. The analysis is conducted experimentally following a cross-layer approach and through the use of properly developed testbed within...
A new digital signal processing method capable of measuring signals typical parameters, such as channel power, channel bandwidth, and carrier frequency, is presented hereinafter. In particular, thanks to some attractive features of the exploited MUSIC algorithm, the method allows the measurement of typical parameters of wideband signals even though they occupy, fully or partially, the same frequency...
