| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We are conducting the research for a future advanced 800MHz-band FPU (Field Pick-up Unit) transmission system which is used in road race relay broadcast. As its transmission scheme, we are studying MIMO-OFDM and adaptive antenna techniques. In order to design and evaluate a new system efficiently, comprehension of actual propagation characteristics and modeling of those are important. Therefore, we examined and analyzed propagation characteristics of actual transmission environment, transmitting OFDM signal of current 800MHz-band FPU from a moving vehicle, receiving at a fixed point located on the rooftop of a building. In this paper, we analyzed time-variant characteristics of the channel due to movement of the transmitter, and tried to model in frequency-domain, focusing on auto-correlation function. And then, we considered parameters which influence the interval in which the channel can be regarded as quasi-static. | |
