the ZDSC. The 10 rays are spaced in angle domain <strong>and</strong> have identical power. The power of each ray is<br />
P n /10, where P n is the average power of the nth ZDSC. The offset angle spacing depends <strong>on</strong> the value of<br />
AS of ZDSC_D for the departure side <strong>and</strong> value of AS of ZDSC_A for the arrival side. The AS<br />
<strong>and</strong><br />
φ<br />
AS are per ZDSC <strong>and</strong> are different from the<br />
ϕ<br />
φ<br />
ϕ<br />
σ <strong>and</strong>σ , respectively, which are the composite<br />
angle-spread involving all ZDSC. The rays of the ZDSC have r<strong>and</strong>om phases. The angle distributi<strong>on</strong>s <strong>and</strong><br />
power azimuth spectrum at the transmitter or receiver sides may vary from <strong>on</strong>e scenario to another. Table<br />
3.8 states the angle distributi<strong>on</strong>s of different scenarios that are defined in WINNER generic <strong>channel</strong><br />
model. The σ <strong>and</strong> σ influence in generati<strong>on</strong> of the ZDSC directi<strong>on</strong>al informati<strong>on</strong> through the<br />
φ<br />
ϕ<br />
parameters r<br />
φ <strong>and</strong>r ϕ , respectively. The locati<strong>on</strong> parameter for all distributi<strong>on</strong>s is zero <strong>and</strong> the scaling<br />
parameters are defined by r φ<br />
σ φ for departure angles <strong>and</strong> by r ϕ<br />
σ ϕ for arrival angles. The generati<strong>on</strong> of<br />
the angle offsets from the rays from cluster mean angle depends <strong>on</strong> AS<br />
φ for departure side <strong>and</strong> <strong>on</strong><br />
ASϕ<br />
arrival cluster. The offset angles are determined by multiplicati<strong>on</strong> of the angles spread per ZDSC<br />
with basis vector of offset angles (BO), e.g., AS<br />
φ *BO. Table 3.9 states the number of ZDSCs <strong>and</strong> the<br />
number of rays in each cluster as well as their AS<br />
φ <strong>and</strong> AS<br />
ϕ for the c<strong>on</strong>sidered scenarios. The angles<br />
of BO vector <strong>and</strong> the calculati<strong>on</strong> of the offset angles are presented in Table 3.10.<br />
