I'm trying to determine whether an application I have in mind is feasible with currently available DSP technology (DSP chips and ADCs).
I want to eliminate an interfering signal using an LMS adaptive filter. I have access to the source of the interference.
The bandwidth of the interfering signal is in the order of 1MHz (maybe a little less, but just as a conservative assumption, let's say 1MHz). The bandwidth of the signal I want to measure can be higher; possibly in the order of 10MHz or 20MHz.
EDIT: I estimate that the application will require sampling at no less than 12-bit resolution.
Does the above sound feasible? Could you suggest some DSP chips that you'd estimate could potentially handle the above workload?
If it sounds like it's not feasible, can you give an estimate of what you think would be the highest bandwidth that current DSP chips could handle?
You may assume that the DSP chip will be doing exclusively this; or maybe just some "lightweight" additional work.
