Abstract :
Adopting a noncanonical structure, redundant signed digit (RSD) arithmetic, and fast radix-4 signed power-of-twos (SPT) conversion, we propose a high-speed LMS adaptive filter architecture with low hardware cost. With this architecture, good performance of adaptive filtering is still maintained
