An IF Digitizing Receiver for a Combined GPS/GSM Terminal
نویسنده
چکیده
For the purpose of traffic telematics (route guidance, fleet management etc.) one needs terminals on the vehicle for the quasi-simulteanuos reception of cellular phone (GSM) and satellite navigation (GPS). A conventional approach uses two complete receivers for this two tasks. We describe a cost-saving solution for a combined receiver which relies on the TDM structure of the GSM signal. Our solution is based on an bandpass-sigma-delta ADC for IF digitizing.

Fine Time Aiding and Pseudo-Synchronisation of GSM Networks
The integration of CDMA and GPS within a single mobile terminal, in support of the FCC E911 initiative, has greatly benefited from the GPS-based synchronisation of the CDMA network. Similar synchronisation is not available in GSM and W-CDMA networks which are, by design, asynchronous in operation, and this makes GPS integration into GSM and W-CDMA mobile terminals more complex and costly. Duffe...
متن کاملNomadic Base Station (NBS): a Software Defined Radio (SDR) based Architecture for Capacity Enhancement in Mobile Communications Networks
Abstract-In this research work, the problem of congestion that leads to dropped calls at GSM cell sites and drastic reduction in network capacity is addressed. We designed a novel GSM base station architecture named Nomadic Base Station (NBS) which is based on Software Defined Radio (SDR) architecture and simulated the LNA for its receiver front-end. The NBS receiver LNA selects and amplifies G...
متن کاملAccurate Determination of GPS Receiver with Different Classification Methods
One of the instruments for determination of position used in several applications is the Global Positioning System (GPS). With a cheap GPS receiver, we can easily find the approximate position of an object. Accuracy estimation depends on some parameters such as dilution of precision, atmospheric error, receiver noise, and multipath. In this study, position accuracy with GPS receiver is classifi...
متن کاملA Wavelet-based Spoofing Error Compensation Technique for Single Frequency GPS Stationary Receiver
Spoofing could pose a major threat to Global Positioning System (GPS) navigation, so the GPS users have to gain an in-depth understanding of GPS spoofing. Since spoofing attack can influence position results, spoof compensation is possible through reducing position deviations. In this paper, a novel processing technique is proposed and the wavelet transform is used to eliminate the impact of sp...
