Hello Simon, >When you do this *please* let's talk about it together and try for a common >code base which works at any sampling frequency. No problem, but I program in Pascal not in C...(Votjech did a C source). The sampling frequency must be 11025, but it is not a problem to work at 8000. In MT63, the sampling frequency is 8000, so I previously do a simple interpolation to switch from 8000 to 11025 for, afterwards, to do the Fourier spectrum used for the RS ID.
If it poses problem I can send you my interpolation procedure. For SdR, it will be more complex (but interesting). 73 Patrick ----- Original Message ----- From: Simon (HB9DRV) To: [email protected] Sent: Thursday, April 16, 2009 8:28 PM Subject: Re: [digitalradio] Mode of the Day? RS ID on SdR bandwidth Hi Patrick, When you do this *please* let's talk about it together and try for a common code base which works at any sampling frequency. Vojtech - does your code run at 8kHz? Simon Brown, HB9DRV www.ham-radio-deluxe.com ----- Original Message ----- From: Patrick Lindecker Hello Simon and all, About detection of any RS ID on all the SdR waterfall (almost 200 KHz of bandwidth) and hence detection of any exotic digital transmission, with the original source it is not possible (due to a too big load on the CPU), but Vojtech added in his code a hashing function. It is surely the good solution. I'm working also on this good idea of Votjech. I hope to propose a new RS ID source with this hashing function, in the future. 73 Patrick
