The steering dynamics of reconfigurable intelligent surfaces (RISs) have hoisted them to the front row technologies that can be exploited solve skip-zones in wireless communication systems. They enable a programmable environment, turning it into partially deterministic space plays an active role determining how signals propagate. However, RIS-based systems' practical implementation may f...

Optical communication modulation technology and networking are two important technologies for constructing free-space optical (FSO) communication. In this paper, pulse width (PWM) is used to realize The process of signal demodulation implemented by means a field programmable gate array (FPGA). An relay system constructed networking. binary data bits in the converted into signals different width...
