摘要: In this paper, multilevel Digital Colour Shift Keying (DCSK) and DCSK using multi-colour LEDs are considered. Moreover, to increase the spectral efficiency of DCSK, Spatial (SCSK) is proposed, in which combined with Space Keying. The symbol error rate SCSK performances evaluated from theoretical analysis simulation analysis, under consideration transmitter-receiver configuration within room. Consequently, when channel gain ratio smaller than 1.7, energy better those Generalised (GSSK), on other hand, improved becomes large. number transmitters large, can be compared DCSK.
