Second-order Mach bands: Chromatic and achromatic

Achromatic second-order (contrast) Mach bands can be perceived near the contrast ramp between two contrast levels. In this study we show that a repertoire of chromatic second-order Mach bands is also clearly perceived, under equal-luminance conditions (minimum motion technique). The results show that chromatic and achromatic second-order stimuli yield significant perceived second-order Mach ban...

Intermodulation Interference in the GSM/UMTS Bands

This paper deals with the additional and not usually considered Intermodulation (IMD) interference in GSM/UMTS Bands. First a simple theoretical background about IMD in radio systems will be presented, followed by a practical application of that theory to a real commercial power amplifier. Finally some practical advices will be given in order to minimize this type of interference.

DME/TACAN Interference and its Mitigation in L5/E5 Bands

The Galileo E5a/E5b signals and the GPS L5 signal lie within the Aeronautical Radionavigation Services (ARNS) band. They suffer interference from the services in this frequency band, in particular, high power pulsed signals from Distance Measuring Equipment (DME) and Tactical Air Navigation (TACAN) systems. The pulsed interference degrades received Signal to Interference and Noise Ratio (SINR),...

Multi-radio Interference Diagnosis in Unlicensed Bands Using Passive Monitoring

OF THE THESIS Multi-Radio Interference Diagnosis in Unlicensed Bands using Passive Monitoring by Akash Baid Thesis Director: Professor Dipankar Raychaudhuri The increasing density and data rate of unlicensed band wireless devices has led to significant interand intra-radio interference problems. Multiple competing standards such as the IEEE 802.11b/g, Bluetooth and ZigBee, all of which operate ...
