July 1991

George A. Hufford, John R. Godwin, and Vincent S. Lawrence

Abstract: If over-the-air High Definition Television (HDTV) is to become a reality it would be useful to know the multipath characteristics of the radio channel over which it will be carried. The Institute for Telecommunication Sciences (ITS) has begun a program to measure these characteristics in locations that might represent consumer habits. This is the second report of the program. It discusses a few details concerning the measurement techniques and describes measurements made in the vicinity of San Francisco, California

Keywords: channel characterization; delay spread; high definition television; impulse responses; multipath; pseudonoise codes; radio propagation; spectra
