|Subject:||Re: [Discuss-gnuradio] Help required for dpsk_loopback.grc|
|Date:||Wed, 4 Mar 2015 11:40:10 -0500|
I am very new to GNU Radio and currently trying to explore the example grc blocks available with the package. For example, I tried to execute the example given in the example folder as "dpsk_loopback.grc" (/home/ubuntu/examples/digital/demod/dpsk_loopback.grc). I have following doubts:
1. There is no readme or document available which can explain about the total block or example in detail. Can I get any tutorial/document which will give complete info about all such examples?? i.e.Each grc example file to be explained in detail. If any such details are available, kindly give me the link for the same.
2. In the subject example, there is a signal source which is generating a cosine wave from 500Hz to 5KHz. This cosine wave after the throttle block is fed to packet encoder. Here, what is the role of packet encoder?? In the packet encoder block properties there are many fields like "samples/symbol", "bits/symbol", etc. These fields are generally related to data, not the analog signal which is fed to it. How does the packet encoder take cosine wave and use the fields like samples/symbol and bits/symbol??? Do we have any document which will explain in detail about all such blocks???
3. I want to analyze the output of packet encoder. How is it possible?? Which block will you suggest to analyze the output???
4. As I am very new to the GNU field and I quite poor in software domain, I would like to get some help in the beginners level. Please provide me any link, if it is available.
