Cognitive Radio (CR) is viewed as a novel approach for improving the utilization of the radio electromagnetic spectrum. The radio spectrum is a scarce resource while wide spectral ranges are only rarely used. Spectrum Pooling enabling public access to these new spectral ranges without sacrificing the transmission quality of the actual license owners. However, in the Spectrum Pooling system, the interference...
Multipath is one of the paramount error sources in code tracking. Optimized Multiple Gate Delay structures have been proposed before for SinBOC(1,1)-modulated signal and infinite receiver bandwidth, in order to cope better with multipath. The new modulation, Composite Binary Offset Carrier (CBOC) modulation, used in Galileo E1 band makes it possible that either SinBOC(1,1) or CBOC reference code could...
