Delay analysis for base station to vehicle communication at 3.35 and 5.4 GHz

This paper presents the delay results of wideband wireless channel measurements conducted in urban environment for base station to vehicle at 3.35 GHz and 5.4 GHz, respectively. Channel impulse responses are collected in both line-of-sight (LOS) and non-line-of-sight (NLOS) propagation. Based on the measurement data, power delay profiles are extracted. Delay statistical characteristics like mean excess delay, root-mean-square delay spread, and maximum excess delay, are calculated and analyzed. It is found that delay spread shows no significant differences in LOS case for the measured two frequency bands, whereas it is larger in high frequency in NLOS case.
