Performance Analysis of Color Shift Keying Systems in AWGN and Color Noise Environment

Abstract

In this paper, bit error rate (BER) performances of the color shift keying (CSK) modulation which is selected as one of the modulation methods in visible light communication systems, are analyzed in AWGN and color noise environments. Red, blue, pink and violet noises are used as colored noise. In addition, the performance of visible light communication systems is investigated by using a single-path channel in indoor environments where the transmitter and the receiver see each other (Line of sight, LOS). Computer simulation studies are performed for 4-CSK, 8-CSK and 16-CSK modulation. It is seen that the best performances of computer simulation results are obtained in red noisy environments after AWGN.
