ETSI ETSI TR 125 943 V13.0.0 (2016-01)63GPP TR 25.943 version 13.0.0 Release 13A large number of paths (20) in each model ensure that the correlation properties in the frequency domain are realistic. Path powers follow the exponential channel shapes in th
26、e COST 259 model. The delay spreads for each model are close to expected medians when applying the COST 259 model in reasonably sized macrocells. In the rural model a direct path is present, resulting in Rice-type fading when filtered to wideband channels. The hilly terrain model consists of two clu
27、sters, a typical situation in these environments. With the chosen parameters the models will be quite similar to the GSM channel models 2, after filtering to the GSM bandwidth. In Section 5, the channel models are specified explicitly. The tap delays have been determined by generating 20 independent
28、 identically distributed values from a uniform distribution in the interval , where is the rms delay spread. For the Hilly Terrain channel 10 paths have been generated for each cluster and for the Rural Area model there is a total of 10 taps. Relative powers have then been calculated using the chann
29、el shapes in Annex A, Table A.3. The channels have been normalised so that the total power in each channel is equal to one. Channel model descriptions Radio wave propagation in the mobile environment can be described by multiple paths which arise due to reflection and scattering in the mobile enviro
30、nment. Approximating these paths as a finite number of N distinct paths, the impulse response for the radio channel may be written as: which is the well known tapped-delay line model. Due to scattering of each wave in the vicinity of a moving mobile, each path will be the superposition of a large nu
31、mber of scattered waves with approximately the same delay. This superposition gives rise to time-varying fading of the path amplitudes , a fading which is well described by Rayleigh distributed amplitudes varying according to a classical Doppler spectrum: where is the maximum Doppler shift, a functi
32、on of the mobile speed and the wavelength . In some cases a strong direct wave or specular reflection exists which gives rise to a non-fading path, then the Doppler spectrum is: where is the Doppler frequency of the direct path, given by its direction relative to the mobile direction of movement. Th
33、e channel models presented here will be described by a number of paths, having average powers and relative delays , along with their Doppler spectrum which is either classical or a direct path. The models are named Tux, Rax and HTx, where x is the mobile speed in km/h. Default mobile speeds for the
34、models are according to Table 5.1. The relative position of the taps is for each model listed with a 0.001 s resolution. =Niiiah )()( iaia5.02)/(1/(1)(DfffS /vfD=v )()(sffS =sf2iai 4,0ETSI ETSI TR 125 943 V13.0.0 (2016-01)73GPP TR 25.943 version 13.0.0 Release 13Table 5.1: Default mobile speeds for

42、he EU, in which there are participants from manufacturers, operators and universities. This forum is the second successor of COST 207, who did the work on which the channel models used in GSM standardization were based. One of the work items identified in COST 259 is to propose a new set of channel
43、models which overcome the limitations in the GSM channel models, while aiming at the same general acceptance. The models are aimed at UMTS and HIPERLAN, with particular emphasis on adaptive antennas and directional channels. A.2 Model descriptions The main difference between the COST 259 model and p
44、revious models is that it tries to describe the complex range of conditions found in the real world by distributions of channels rather than a few typical cases. The probability densities for the occurrence of different channels are functions of mainly two parameters: 1) Environment 2) Distance Give
45、n a certain environment (e.g. Urban Macrocell) and a certain distance (or distance range/cell radius), the parameters describing the distribution functions for this particular case can be extracted. Performing a sufficient number of channel realizations will give a distribution of channels which giv
46、e a much better representation of reality than what would be possible using only one channel. The environments identified so far in COST 259 are given in Table A.1, although these are by no means written in stone. The macrocellular environments have the same names as the GSM models. (It is being dis
47、cussed if there should be a distinction between indoor and outdoor mobiles for the macrocellular environments.) Table A.1: Preliminary environments identified by COST 259. Macrocell Microcell Picocell Typical Urban (Street Canyons) (Tunnel/Corridor) Bad Urban (Open Places) (Factory) Rural Area (Tunn
48、els) (Office/Residential Home) Hilly Terrain (Street Crossings) (Open Lounge) In COST 259, a number of properties of the propagation channel has been considered in the model work. The full proposal will include all of these properties, but it is quite simple and straightforward to implement the mode
49、l in a modular structure, so that each of the properties (listed in Table A.2) can be switched on or off individually depending on the application. Inherent in the model is also correlations between the properties, e.g. time dispersion and shadow fading are modelled as being partially correlated.
