Abstract: A method and an apparatus for polarization multiplexing and encoding in a visible light communication system based on a gold nanoparticle are provided. A method for encoding in a receiver using a polarizing characteristic in a visible light communication system based on a gold nanoparticle, which is performed by a computer device, includes splitting a receive signal into left circular polarization light and right circular polarization light by allowing the receive signal to pass through a linear polarizer and estimating a phase retardation difference, and detecting a transmit symbol by estimating the phase retardation difference.
