Abstract :
By describing the principle and parameter selection guide in detail, M×N-ary variable width period modulation (MNVWPM) is proposed in this paper to increase the bandwidth efficiency for ultraviolet communication (UVC) through intensity modulation and direct detection. Theoretical analysis and experimental results indicate that, MNVWPM can be used to achieve a bandwidth efficiency higher than those of commonly used on-off keying (OOK) or pulse position modulation (PPM).
