Based on radio chip specifications, a digital DC removal high pass filter is necessary after RxHP is set to zero. I am trying to design a HPF with stopband as 10K and passband start at 30KHz using Elliptic IIR with Matlab fdatool. However, the filter designed has a negative impact on the decoding performance.
I would really appreciate it if WARP team could share some knowledge and experience in tackle this problem!
