An interesting signal modulation

With GIOVE-B, the second satellite of the IOV Galileo constellation, a new modulation is being experimented, the CBOC(6,1,1/11).
With the CPLD version of NSL dongle and a bit of software, I did get the result below.. is not smooth and as beautiful as Septentrio's one (http://www.septentrio.com/news_news.htm), but it demonstrates some interesting capabilities already.

Fig.1: Tracking the CBOC(6,1,1/11) with a BOC(1,1) replica, a BOC(6,1) replica, and the sum of of the two.

In a couple of week I would like to show something else... let's see.
