- Abstract
- The wideband characteristic, a delay spread of multipath signals, was measured with a channel sounder at various environments. The environments were divided by three parties. The measurements in each environment were done in line-of-sight case at carrier frequency of 8.05 GHz. The channel sounder was acted by PN mode, 100 Mcps, 10 ns resolution, and maximum delay time was 40.96 μs. From the measurement results, RMS delay spread at downtown area of a large city is the biggest among them. The reason is some multipaths due to dense arrangement of high-rise buildings, lower height of transmitter antennas than height of buildings, and heavy traffic. ©2007 IEEE.
