“…Unbiased finite memory DPLL (UFMDPLL) was proposed in [10] to overcome the drawbacks of KF-based DPLL. UFMDPLL is based on the finite impulse response (FIR) filter [12,13,14,15,16,17,18,19,20,21] using only recent finite measurements, and it showed superior robustness against computational errors than KF-based DPLL.…”
