Re: [Discuss-gnuradio] Fwd: Proposal for GSoC on gr-gsm

Great thanks to all of you here and in melange! The content below is updated according to the advises above: 1.More details in time synchronization and burst extraction; 2.More details in using streamed tag to get more stable frequency resetting; 3.More details in frequency correlation; 4.A state m

Re: [Discuss-gnuradio] Fwd: Proposal for GSoC on gr-gsm

Hi, My proposal has been updated on github. The proposal has been changed a lot according to the comments on Melange. 1.The flow graph has been changed. A new architecture is designed. 2.A state machine is added which explains more details on GSM decoder. 3.The deliverable list has been changed.

Re: [Discuss-gnuradio] Fwd: Proposal for GSoC on gr-gsm

The figure in the previous mail is incorrect. It is too weird that the ratio is so low and with narrow transition. And the sample count is not match the FB. After some debugs, I found the reason. I got the sample data with GNU Radio companion. When I execute the flow graph, it starts to write data

Oh, I forgot to say. The data is sampled by a RTL-SDR. Zhenhua 2014-03-13 11:25 GMT+08:00 zhenhua han : > Hi, > > I have implemented the algorithm in the paper for test and uploaded my > code to github. > > https://github.com/hzhua/gr-fchdetection > > The result given by the algorithm seems gre

Hi, I have implemented the algorithm in the paper for test and uploaded my code to github. https://github.com/hzhua/gr-fchdetection The result given by the algorithm seems great. Here is a figure generated by my program which is the ratio of average error power to input power. It is very low at

Re: [Discuss-gnuradio] Fwd: Proposal for GSoC on gr-gsm

I totally agree with Martin regarding PFB channelizer. The PFB for gsm will be also a good challenge for gnuradio in general as obtaining only a moderate number of channels(say 50) takes a lot of processing power and achieving realtime processing is not possible currently. Split per thereads and
