Hi, I don't have any code or implementation. Just some thought. In my opinion, implementing cell search on gnuradio in realtime could be quite hard. Even with the aid of hardware accelerator such as decorrelator, cell search is computationally intensive in real modem. In gnuradio, all these compu

Hi Theo.. In GRC, you can use File Source block for using signals from the sample files. You can also make use of Signal Source, Noise Source, Audio Source (input from sound card) and so on... For visualizing you can have FFT Sink, Oscilloscope Sink, Numeric Sink and so on.. Happy experimenting..
