can you go inside the gr-cdma directory and do "ls -l". you should see several directories like apps, python etc. Now do "pwd" in the linux prompt and let us know the result. On Tue, Sep 29, 2015 at 8:43 AM, alfred noble wrote: > Thanks > My operating system is Ubuntu

It is possible I think. The current synchronization method only uses the inserted preambles. If you don't change the preamble, it will not affect the synchronization. You may add a Code block into the transmitter diagram, also you need to change some parameters of other blocks. But for the
