Abstract

Optical wireless communication employing 16-state trellis-coded multiple-subcarrier modulation with a fixed bias is introduced, where 4-dimensional vectors having the largest Euclidean distance for 32 signal points are used. After combining coding with the 4-dimensional modulation, the proposed system improves the power and the bandwidth efficiency, significantly. The performance evaluation results are that the normalized power and the bandwidth requirements are reduced up to 6.1 dB and 5.8 dB compared to those of the block codes using QPSK, respectively. The proposed system needs much less power and bandwidth than the counterparts transmitting the same bit rates for optical wireless connection.
