This paper presents a method to improve implementation accuracy of a recently proposed CORDIC ARMA lattice filter. Since the CORDIC ARMA lattice filter algorithm has a problem in its shift sequence, i t cannot implement a lattice filter accurately. Therefore, in this paper we apply the shift sequence proposed by Walther without the problem to the CORDIC ARMA lattice filter, and then we realize ...

Understanding the statistical fluctuations of lattice observables over gauge configurations is important both theoretically and practically. It provides physical insights to tackle famous signal-to-noise problem sign problem, inspires new thoughts in developing methodologies improve signal calculations. Among many efforts, exploring connections between real imaginary parts numerical results a n...
