摘要: Colour Shift Keying (CSK) modulates the intensity of multi-colour light emitting diodes (LEDs) for information transmission in visible communication (VLC). Currently, no work has been published which details performance this standardised modulation scheme that can be used by CSK developers as a baseline. In work, various colour band combinations (CBCs) multilevel are studied and their over an additive white Gaussian noise (AWGN) dispersive optical wireless channel is detailed. The analysis evaluation suggests spread BER performance, i.e. all do not have same performance. For AWGN channel, CBC-2 (CBC no. 2) electrical SNR gain up to 2.5 dB other eight CBCs CSK. also most robust CBC channel.
