| Abstract(in English) | This paper presents in-laboratory system verification results of a hyper-multipoint data gathering satellite communication system. The developed system can effectively aggregate various types of sensor data from a number of observation stations spread over nation-wide areas by exploiting a highly efficient access control algorithm, a precise frequency synchronization scheme and a FFT-type block frequency demultiplexer, all of which are newly proposed. Experimental verification results show that; the developed system achieves required channel allocation specifications (bandwidth: 1kHz min., channel separation: 1kHz min.); multiple observation stations can satisfactory transmit the data without mutual interference. |
