| Abstract(in English) | This report analyzes the distance dependence of delay profiles measured in an uraban area. Frequencies of 3.35 GHz, 8.45 GHz and 15.75 GHz and 50 Mchip/s psuedo-noise chip rate are used in this measurement. The site-dependence of radiowave numbers are extracted from the measured delay profiles, and then the bit error rates and eye aperture ratios are predicted at a lower symbol rate compared to the chip rate. The evaluations show that radiowave number is not distributed uniformly with respect to distance and that there are several locations where the strongest wave is dominant. The bit-error-rate and eye-aperture-ratio estimations show that partial degradation of the transmission performance occurs even in near the transmission point. |
