Oh, I forgot to say. The data is sampled by a RTL-SDR.Zhenhua2014-03-13 11:25 GMT+08:00 zhenhua han <address@hidden>:
Hi,I have implemented the algorithm in the paper for test and uploaded my code to github.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 frequency burst and high at other bursts.I have also added this part in my proposal.

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 VOLK should be taken in consideration.

You should definitely check out the PFB channelization, though. For
multi-ARFCN applications, this will always be a requirement.
