Enhanced Code Acquisition in Global Positioning Radio Systems

چکیده
Satellite-based localization using the global positioning systems (GPS) has attracted ever growing attention in the last few years. In this work, we present a signal processing technique for initial code acquisition and synchronization of a GPS signal, such as the one used by position location techniques in 3G wireless scenarios. Several computer simulations have been accomplished to validate the proposed PHD method for the acquisition and synchronization of a GPS signal, under a possible systematic frequency error or a nominal frequency offset. The numerical results obtained from our simulation trials confirm the validity of such approach which overcomes the conventional non-coherent techniques.

Compensation of Doppler Effect in Direct Acquisition of Global Positioning System using Segmented Zero Padding
Because of the very high chip rate of global positioning system (GPS), P-code acquisition at GPS receiver will be challenging. A variety of methods for increasing the probability of detection and reducing the average time of acquisition have been provided, among which the method of Zero Padding (ZP) is the most essential and the most widely used. The method using the Fast Fourier Transform (FFT...

Continuous Wave Interference Effects on Global Position System Signal Quality
Radio interference is one of the major concerns in using the global positioning system (GPS) for civilian and military applications. Interference signals are produced not only through all electronic systems but also illegal jammers. Among different types of interferences, continuous wave (CW) interference has strong adverse impacts on the quality of the received signal. In this paper, we make m...

Internet of Things” (IoT) requires information to be collected from “anything”, “anytime”, and “anywhere”. In order to achieve this, wireless devices are required that have (1) automatic data acquisition capability, (2) small size, (3) long life, and (4) long range communication capability. One way to meet these requirements is to adopt active Radio Frequency Identification (RFID) systems. Acti...
متن کاملLow Complexity Long PN Code Acquisition Scheme for Spread Spectrum Systems
In this paper, a low complexity long pseudo noise (PN) code acquisition scheme is proposed for spread spectrum systems including global positioning system (GPS) and code division multiple access (CDMA) system. By using a phaseshift-network, the proposed scheme has less complexity than the conventional dual correlating sequential estimation scheme. From the analytic and numerical results, it is ...
