A Walsh-Hadamard Transform Adaptive Filter with Time-varying Step Size.

가변 스텝사이즈를 갖는 월시-아다말 변환 적응 필터

we propose the Walsh-Hadamard Transform adaptive filter with time-varying step size. The performance of the proposed algorithm is evealuated in system identification where computer simulations are performed for both time-invariant and time-varying system. It is shown that the proposed algorithm produces good results compared with similar algorithms under different conditions, particularly in case of time-varying circumstance.
