摘要：
The problem of fast code acquisition in dual-band Galileo receivers is tackled. The proposed techniques exploit the Galileo E1 and E5 Open Service signals structure, implementing a cross-band aiding approach that yields mutual assistance in code synchronization adopting a master/slave configuration. The schemes are analyzed in terms of mean acquisition time (MAT) introducing the procedure flow-graph and overall mean acquisition time (OMAT). Numerical evaluation shows enhanced OMAT performance w.r.t. autonomous dual-band acquisition, guaranteeing complexity reduction.
