The upcoming Galileo global navigation satellite system has a design problem with the cosine-phased BOCc(15, 2.5) modulation\nof its Public Regulated Service (PRS A-code). This signal needs far more bandwidth than the available 40.92 MHz. The present\nsignal and system specification cannot be expected to deliver design performance under practical operational conditions (noise,\nreceiver phase distortion, and multipath). There would not have been this problem with sine-phased BOC(15, 2.5).
