The first stage of processing within a GPS receiver consists of the signal acquisition process,
the output of which provides a rough estimation of code delay and Doppler frequency. The …

This thesis provides a comprehensive analysis of the acquisition performance of the mobile-
embedded Global Positioning System (GPS) receiver. Particular emphasis is given to the …

In this paper, we propose a search technique that takes advantage of multipath, which has
long been considered deleterious for efficient communication, to aid the sequence …

This survey guides the reader through the open literature on the principle of initial
synchronisation in single-antenna-assisted single-and multi-carrier Code Division Multiple …

In this paper, the problem of code acquisition for spread-spectrum systems is investigated in
the presence of frequency errors. The classic approach of noncoherent post detection …

In urban environment Global Navigation Satellite System (GNSS) signals are impaired by
strong fading and by the presence of several potential sources of interference that can …

In the context of spread spectrum communications, this paper investigates the use of
likelihood ratio testing techniques for the design of post detection integration (PDI) methods …

A threat to GNSS receivers is posed by a spoofing transmitter that emulates authentic
signals but with randomized code phase and Doppler values over a small range. Such …

This paper addresses the problem of robust frame synchronization for TDM/TDMA systems
in the presence of frequency errors, accomplished through data-aided recognition of the …

Since the development of the GPS, the global navigation satellite systems (GNSS) have
been widely diversified: maintenance, modernization and deployment of new systems such …
