| Abstract(in English) | In order to obtain a high received optical signal power for non-directed diffuse indoor optical wireless communication system, a multi beam transmitter system has been proposed. For the case of high data transmission rate, however, the performance of multi beam transmitter system is much degraded because of the ISI caused by increased delay spread. In this paper, in order to suppress the delay spread of multi beam transmitter system, we propose two delay spread suppression methods, and evaluate the performance improvement achieved by proposed methods. Numerical results show that, by using proposed methods, the delay spread of multi beam transmitter system is suppressed and multi beam transmitter system can achieve better performance in high data transmission rate. |
