PROJECT TITLE :

Analysis and Design of Three-Stage Concatenated Color-Shift Keying

ABSTRACT:

Visible lightweight communication (VLC) relies on abundant unlicensed bandwidth resources. As an engaging high-data-rate modulation scheme designed for VLC, color shift keying (CSK)-assisted modulation is analyzed. We tend to commence our study from an uncoded -CSK theme looking forward to the joint most-likelihood (ML) arduous detection (HD) of three colors when communicating over an AWGN channel, where each empirical and analytical results are provided. We have a tendency to invoke extrinsic info transfer (EXIT) charts for planning a Most a posteriori chance (MAP)-based soft detection (SD)-aided iterative receiver jointly detecting the 3 colours. Primarily based on the EXIT characteristics of -CSK, we tend to design different signal labeling methods for various color constellations and detection schemes, which are capable of achieving a substantially improved bit-error-rate (BER) performance. So, given fastened transmission power, a CSK system using our proposed signal labeling is capable of accelerating the reliable data transmission distance by about thirty%.
