Statistical analysis of delay spread in distributed antenna systems
Xiaodong Wang · Journal of Shandong University · 2012
The statistical properties of delay spread in a two-path distributed antenna system were analyzed,of which each path was characterized by Rayleigh fading and lognormal shadowing.As a special case,the statistical properties of delay spread in single scale alone fading environments were also obtained.Finally,a Monte Carlo simulation model was constructed using the channel parameters under typical urban environments,and the derived expressions were validated by simulation results.Because the root mean square of delay spread depended on many parameters,the effect of one specified parameter was considered under the condition of other parameters being fixed according to the practical scenarios.
