DVB T2 Research at University Level

[V.Jeewa]

Dear Oliver

I have retired as a Broadcast Engineer at a local TV Station and moved to academic life at a University in Malaysia.

I intend to do research into DVB and my main focus is on PAPR Reduction and codes especially LDPC.

I have to submit a research proposal with a low cost budget of perhaps $10,000. I need your advice on the type of extra equipment which I can use with DVBT2-CSP . However even if the cost exceeds $10,000 ,the authorities may consider the proposal provided it is beneficial to the country.

Thank you.

Hi,

As you know, the CSP itself is a simulation, and all that's required to run it is a computer and a licence for MATLAB (including a couple of toolboxes). Thanks to the work of Chrisvdw it's also possible to run it in the open-source Octave package.

As for extra equipment, it really depends on what you want to do but there are a number of options within your budget.

If you want to process and generate real-world signals, you could think about the gnuradio project and in particular the various hardware platforms that it supports. You should at least be able to use this to play out signals generated by the CSP. Note however that the CSP itself runs orders of magnitude slower than real-time.

If you want to test receivers or carry out other experiments, there are several proprietary products, including PCI cards, that can be used to generate or receive DVB-T2 signals, as well as recording and playing back I/Q files.

Thank you.

I have a problem now. I have bought a new laptop with Windows 8.1 and reinstalled DVBCSP and Matlab 2013a. However DVBCSP cannot run on it stating there is no compiler.There was no problem with previuous Windows version.

I have tried to download Windows 7 SDK but the computer could not accept it. The Windows 8.1 can probably be downloaded but there is a notice that there is no compiler and that why I have hesitated to download. There are 2 another alternative which I am contemplating:

a) Installing a separate C compiler

b) Purchasing Windows Studio 2013 from Microsoft for download which states that it does have a compiler

Therefore I need a direction now.

Hi.

This problem is not related to the CSP, it's simply about getting mex files to compile on Windows 8. You are more likely to get support on forums related to MATLAB than on here. If you google "MATLAB mex Windows 8" you'll find that you're not the first to have this problem and that others have managed to make it work. This is the first hit and suggests several things, including a link to this page.

Good luck!

Thank you. I am following Matlab forum now
