The generation of channel parameters is performed per channel segment. During each channel segment
the AoAs and AoDs, and delays of each ZDSC are fixed while the channel goes through fast fading
according to the virtual motion of the MS, which has a velocity vector v. The assumed system has S
antennas at the transmitter side and U antennas at the receiver side. The WINNER generic channel model
is a geometric-based stochastic model. There are a large number of random variables that are incorporated
in the modelling approach. Hence, many parameters must be fixed within the simulation run to make the
computation time feasible. These parameters may differ from one scenario to another. For instance the
ZDSC angle-spread ( AS or AS ) is fixed for all departure and arrival ZDSCs but may have different
φ
ϕ
angles. These parameters represent some of the characteristics of different scenarios.
To obtain MIMO channel coefficients the following steps are followed:
1) Select one of the scenarios to be simulated: A1, B1, B3, C1, C2, or D1.
2) Assign locations of transmitters (BS), receivers (MS), separating distance and their antenna
orientations. The orientation of MS antenna is drawn from iid uniform distribution U(0 o ,360 o ).
Assign velocity vector to each MS. Assign LOS situation to each location according to the
probability.
3) Calculate the path loss associated with transmitter-receiver of every MS and every BS if needed.
4) Generate the vector ?( x, y)
