Hi Mathieu, You can certainly use the UHD to get the signal of interest, but what you are asking is really a question of signal processing and independent of the UHD and any USRP you may be using.
I suggest you focus on the signal processing problem of separating two closely-spaced signals and maybe do some pencil and paper work and then simulation using MATLAB, Octave, SciLab, or even plain old C/C++. Whatever you come up with you can then plug into a UHD-based program that receives samples. Personally, I’d just copy one fo the receive examples and start modifying it to accept your algorithms. If you have not already found it, a good place to start is this book As a person new to this list, please consider that its focus is on things directly related to USRPs and UHD. Your question is probably better posed at Signal Processing Stack Exchange good luck, steven Steven Knudsen, Ph.D., P.Eng. www. techconficio.ca www.linkedin.com/in/knudstevenknudsen All the wires are cut, my friends Live beyond the severed ends.

I would like to implement two bandpass filters and look at the output of both filters, but I am not sure how to proceed. Is it feasible using the UHD C++ libraries ?
