[Discuss-gnuradio] Looking for tutorials (was: Hi all)

[Marcus Müller]

Hi Nirmala,

could you try to use descriptive subject lines in the future? I took the freedom of changing yours, so that people know what your mail is about, in hopes you get better answers that way!

Anyway, Ben is right, you should probably start with the established tutorials at http://tutorials.gnuradio.org.

Your task

First I want to send a simple tone within 20 kHz, sample it and transmit with a high frequency carrier in the ISM band and receive it. 

does sound very feasible for someone who's read the first few chapters of that, although

First I want to send a simple tone within 20 kHz, sample it

is a bit misleading: your tone is a digital signal, as it gets created within your PC; you can't sample it, it's already digital :) But seriously, you can generate a 20kHz with a single block (signal source), and actually send it by connecting that block to e.g. a USRP Sink (if you have a USRP). But you said you wanted a simulation, so I'm a bit left to wonder what to simulate – you see, GNU Radio (and software defined radio) often, if not usually, deals with equivalent baseband so that we don't actually care about the carrier at all, but model all things that happen in the RF passband as happening in baseband. So, your choice for a first simulation seems a bit unusual, if not even slightly unlucky.

Best regards,
Marcus
