Abstract

Infrared communications employing the 4-dimensional Multiple-Subcarrier Modulation with fixed bias for wireless LAN is introduced. In the proposed system, computer simulated 4-dimensional vectors having the largest Euclidean distances are used. After the vectors are applied to the 4-dimensional modulation, the power and the bandwidth efficiencies of the infrared communication system are improved. From the performance evaluation results, the normalized power and the bandwidth requirements of the proposed system are improved up to 1.8 dB and 1.4 dB compared to those of the conventional schemes using QPSK, respectively. The proposed system needs less power and bandwidth for optical wireless connection to fulfill the requirements of the standard.
