| Abstract(in English) | As a multiple access scheme in hybrid line-of-sight (LOS) indoor optical wireless communication system, intensity distribution-based spatial time division multiple access (SD/TDMA) system has been proposed. In the SD/TDMA system, the number of terminals which simultaneously transmit their optical signal to access point (AP) is determined by the discriminability of the transmitted intensity distributions. In order to ensure a required discriminability of the transmitted intensity distributions, terminals with low discriminatory of the intensity distributions are allocated to the different time slots. Because the throughput performance of each terminal depends on the number of required time slots and the increase of the number of time slots degrades throughput performance of each terminal, the decrease of the required time slots is an important issue in the SD/TDMA system. As a countermeasure to enhance the discriminability of the transmitted intensity distributions without increasing the required time slot, this paper proposes transmission power control (TPC) technique. Numerical results will show that throughput performance of SD/TDMA with proposed TPC technique is much higher than that without TPC. |
