Re: DVB-T2 pilot insertion PN sequence used in the reference sequence
The relevant part of the specification is the part immediately above the note that you are quoting, that says "The sequence (pn0, pn1...pnNPN-1) of length NPN =LF, shall be formed by taking the first NPN bits from an overall PN-sequence. The overall PN-sequence is defined by table 56, and each four binary digits of the overall sequence are formed from the hexadecimal digits in table 56 taking the MSB first."
i.e., you should literally take the sequence from the table. The note is simply informative and explains how the sequence was arrived at, but it's the hex sequence in the table that specifies the sequence to be used. So you can just copy the hex string into the MATLAB code and convert it as required.
The DVB-T2 group are hoping to upload a release of an open source T2 coder/decoder software platform to SourceForge sometime this week, and there are also test streams available ( **broken link removed** ). Both of these might be useful to you. Particularly the simulation platform, since it's in MATLAB already. The SourceForge project at
DVB-T2 Common Simulation Platform | Download DVB-T2 Common Simulation Platform software for free at SourceForge.net has been created but there is no code there yet.
I hope this helps.
