But, for eigenmode channels [CHÖB04], that consistently about 10% of the routes the model does not perform underestimated cluster spreads. well, especially when the BS is above rooftops and the In the UWB band from 3.1 to 10.6 GHz, Haneda et al. mobile sunk into a high-rise urban structure.

The contributions from distant scatterers are missing results are given in Table 4.7-14 and are lower than the ones [DEESGK02b]. documented above, probably due to the short paths, the An approach of analysing large sets of measurements light construction and the relatively small size of the was taken by Trautwein et al.

The entries in the last column of Table 4.7-14 the amount of diffusely scattered power using the Rimax refer to the amount of power that could be recovered by estimation algorithm pioneered by Richter and Thomä the SAGE algorithm, indicating that roughly a quarter to that jointly estimates AoA, AoD, delay, Doppler, and half the power could not be modelled, see the next section. polarisations [TLRT05a], see also Section 4.7.4.4. After subtracting the estimated coherent information from the Diffusely scattered power channel transfer, the algorithm parametrises the residual, using the delay domain, into noise and an ex
