2.2 LOS scenario Channel realizations for LOS are achieved by the following procedure: Set the conditions as per the NLOS case. Step 1 and Step 2: Generation of direct clusters. Step 3: Direct clusters consist of three direct clusters,(i = 0,1,2). Generate delay time , arrival angle departure angle and relative power (i,d) normalized against the DA,i(i,d), DG,i(i,d) PDPD,i first cluster’s power as follows: (s) (163) degrees (164) degrees (165) (166) Generation of scattering clusters Step 4: Generation of delay time for scattering clusters Step 4.1: Scattering clusters consist of (– 3) clusters. a) The PDP for scattering clusters is given by: dB (167) b) Calculation of maximum time The maximum delay time is calculated to satisfy the following equation: (168) Solving the above equation yields the maximum delay time . is generally given by . LSth Generation of delay time, relative power, departure angle, arrival angle, and relative Step 4.2: power considering short-term variation for scattering clusters. This step is completely the same as to in the NLOS case. Step 3 Step 5 Generation of the power delay profile Step 5: Generation of relative power Step 5.1: a) Dynamic delay time of each cluster The delay time interval is calculated as follows: (169) The dynamic delay time is generated by using a random number: (170) Where Random[0,1] denotes a random value with uniform distribution between 0 and 1. b) Fixed delay time of each cluster Instead of the dynamic delay time, fixed delay time is given as follows. Table A1-46 shows the L(i) normalized fixed delay time When the number of clusters and the maximum delay time are given, the fixed delay time is calculated by using Table A1-46 as follows: L(i) (171)
