| Abstract(in English) | We developed a cost-effective, high efficient and wide dynamic ranged radio wave transmitting system using an LN optical modulator for Digital terrestrial TV broadcasting. In this paper, an AGC method which can operate for multi-channel OFDM waves (maximum 8 channel) that are transmitted simultaneously, and a study on the use of DFB-LD in stead of YAG laser for the optical source for the cost reduction, obtaining high efficiency for compact sizing are mainly described. Although employing these new methods mentioned above, we still obtained higher C/N more than 50dB that were better than conventional ones. |
