  Abstract

Since reconfigurable intelligent surface (RIS) has the great potential that can design the communication channel as intended, it has been considered as a promising technique for future communication systems. In this paper, we propose a reflection matrix selection technique which selects the best reflection matrix, which achieves the highest secrecy rate in the downlink cellular network with multiple eavesdroppers. The proposed technique achieves better performance than the conventional techniques where no RIS exists or the RIS utilizes a random reflection matrix.
