Abstract

We analyse the performance of parallel combinatory multiple-subcarrier (PC-MS) optical wireless communication system. The PC-MS system can transmit more information at each symbol interval than conventional MS systems with the same subcarriers. In addition the PC-MS system can decrease the bias that must be added to the MS electrical signal, because the number of subcarriers other than null subcarriers is smaller than that in the conventional MS systems and thus the minimum power becomes larger. Therefore, the PC-MS system can decrease the required energy per bit.
