Broadband channel measurement and analysis

An outdoor propagation measurement campaign for beyond 3G (B3G) as well as a wide-band indoor measurement campaign have been performed recently in Beijing, China, in which the sounding signals are transmitted by an one-antenna base station and received by a two-antenna mobile receiver operated at 3.49 ∼ 3.51 GHz bandwidth. Different scenarios: stationary line-of-sight (LoS), stationary non-LoS (NLoS) scenarios, and dynamic NLoS are deliberately chosen in a classic urban environment and office environment The initial results are presented in this article. Parameters including vector channel impulse response, path loss, rays number, excess delay spread etc. are extracted, analyzed, and briefly reported here.
