The Factored Correlator Model (FCM) is an analytical model for the outputs of a GNSS receiver's correlators. The FCM precludes the need for simulation of the lower-level signal processing stages, significantly increasing simulation speed and considerably decreasing processing and memory requirements, while still keeping a high level of realism. Results for the FCM validation using statistical models...
A wireless sensor network (WSN) is a wireless network consistsing of spatially distributed autonomous device using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants at different locations. A complete model of a sensor network is needed to improve upon its efficiency and design.Using a modeling and simulation...
This paper presents an original development methodology for the use of SystemC to model an executable model of a wireless network system. SystemC methodology allows the model to be reconfigurable for extensive early architectural analysis and easy re-mapping to new wireless standards and applications at numerous levels of abstraction. On the other hand network protocols have many complex concurrent...
Electromagnetic interference (EMI) is part of electromagnetic compatibility (EMC) handling all issues of non-intentional interference between transmitters and receivers. In this document, various models and methods are described in order to carry out EMI simulations and evaluate the performance degradation of cosite equipments of a system. A next step will consist in validating the developed EMI simulation...
This paper presents a systematic measurement campaign of diversity reception techniques for use in multiple-antenna wearable systems operating at 868 MHz. The experiments were performed using six time-synchronized bodyworn receivers and considered mobile off-body communications in an anechoic chamber, open office area and a hallway. The cross-correlation coefficient between the signal fading measured...
