Abstract: Although the emerging reconfigurable intelligent surface (RIS) paves a new way for next-generation wireless communications, it suffers from inherent flaws, i.e., double-fading attenuation ...
Abstract: This paper proposes a novel cooperative double-faced active reconfigurable intelligent surfaces (Co-DFA-RIS) architecture to ensure secure transmission. Two DFA-RISs work cooperatively ...
Formal languages and automata are fundamental concepts in computer science. Pushdown automata form the theoretical basis for the parsing of programming languages. Finite automata provide natural data ...
