Abstract—In this paper, we focus on multipath channel characteristics of low–height antenna links for mobile to mobile
communications in urban street canyon environments. We present a wideband MIMO channel sounder and antennas used tomeasure multipath channel characteristics in the 3.7GHz frequency band and the result of calibration test to evaluate a system
performance before field measurement. We carried out channel measurement campaigns in typical urban street canyon
environments in Seoul, Korea. The root mean square (r.m.s.) delay spread and angular spread characteristics are analyzed withresults of their distribution and cumulative density function (CDF) in line of sight (LoS) and non-LoS (NLoS) case respectively.
Keyword—Mobile-to-Mobile, multipath characteristics, channel model, channel measurements, channel sounder
