M-ary SS code added LED-ID system without multiple tag interferences

In this paper, we proposed M-ary SS(Spread Spectrum) code added LED-ID system without multiple tag interferences(MTI). The term LED-ID is entitled by corresponding author, and it is defined as LED based ID and tag system. LED-ID consists of a lot of tags and ID receiver. Recently, LED-ID system faced to MTI problem and enhancement of transmission capacity. As one solution to overcome MTI and transmission capacity problems, we proposed M-ary SS code added LED-ID system. From simulation and performance analysis, we certified that the proposed scheme has no multiple tag interferences with enlarged data transmission capacity.
