Description

This paper describes a measurement of multipath characteristics with microwave link in 7GHz band, a new window function used in Fourier analysis and relationship between multipaths and quality grading of impaired television pictures. The measurement hasn't been possible because its transmission line is not linear. But we measured the characteristics using its group delay characteristics only. As a result, there exist plural multipaths on each transmission line. And some of them have long delay times for example 1470ns long. Also we have developed a new window function that gives a high resolution of this measurement, and resolve two multipaths with 60ns difference in time. Further more, we study the DU ratio that is required for transmitting pictures without impairment.
