Binary offset carrier (BOC) signal synchronization is based on the correlation between the received and locally generated BOC signals. Thus, the multiple side-peaks in BOC autocorrelation are one of the main error sources in synchronizing BOC signals. Recently, a new correlation function with no side-peaks was proposed for sine or cosine phased BOC signal synchronization by the authors [7]. In this...
Binary offset carrier (BOC) signal synchronization is one of the most important steps to recover the transmitted information in a global navigation satellite system (GNSS) such as Galileo and global positioning system (GPS). Generally, BOC signal synchronization is achieved based on the correlation between the received and locally generated BOC signals. Thus, the multiple side-peaks in BOC autocorrelation...
This paper analyzes the tracking performance of a delay lock loop (DLL) using chip waveform shaped code on direct sequence/spread spectrum (DS/SS) systems in multipath environments. In this paper, chip waveform shaping (CWS) filters consider a rectangular (RECT) filter and a raised cosine (RC) filter. It is assumed that a tracking scheme for code synchronization in a DS/SS system uses a single delta...
Binary offset carrier (BOC) signal synchronization is one of the most important steps to recover the navigation data in global navigation satellite system (GNSS) including Galileo and global positioning system (GPS). The main error sources in synchronizing BOC signals are the multiple side-peaks in the BOC autocorrelation and the multipath delay. Recently, a novel correlator receiver for the BOC signal...
In this paper, we propose optimal and suboptimal serial code acquisition schemes for chip-asynchronous direct-sequence spread-spectrum (DS/SS) communications. The conventional serial code acquisition scheme individually compares each value of the correlator outputs with a threshold. Such a scheme is optimum, however, only under the chip-synchronous assumption that it is actually very difficult to...
