Tapped delay line channel models for indoor MIMO radio channels at 5 GHz

In this paper, the modeling methods for developing tapped delay line (TDL) channel models are introduced for MIMO radio channels. Under the assumption of WSSUS channels, the TDL models with dense and dense-sparse taps were introduced in this paper based on indoor MIMO measurements at 5 GHz. Meanwhile, the tap amplitude distributions, Doppler spectra, tap correlation matrix, and power matrices have also been derived.
