Performance evaluation of a new tapped-delay-line model for indoor MIMO channels

A new tap-delay-line (TDL) channel model based on indoor radio wave propagation characteristics and measurement data is developed in this paper. It can estimate the mean power delay profile (PDP) simply and effectively for the LOS and NLOS routes. The model is proven to be consistent with the measurement results. Under the assumption of the WSSUS channels, the tap frequency correlations, tap amplitude distributions, tap Doppler spectrum and the tap space correlations are analyzed as well to find new ways to evaluate a TDL model. The channel models and parameters studied in this paper are important for indoor MIMO channel modeling and simulations for new radio system at 5GHz.
