Approximate Close-Form Solution of Root-Mean-Square Delay Spread in Reverberation Chamber

In this study, reverberation chamber (RC) was used as a wireless channel simulator as root mean square delay spread (RMS-DS) between antennas was adjusted through applying different loadings. Based on the measurement and theoretical analysis, an approximate close-form solution has been developed to explain the quantitative relationship between the RMS delay spread and the parameters of loading. This solution has been proved to be valid in different loading conditions with a wider frequency band.
