Hello,
I am using vienna DL SLS code.
I want to know the diffenrece between the multiple drop and Vienna simulator(Single drop&mobility).
Is there a difference in performance?
——————————————————————————————–
Definition of drop:
A “drop” is defined as one simulation run over a certain time period.
A drop (or snapshot or channel segment) is a simulation entity where the random properties of the channel remain constant except for the fast fading caused by the changing phases of the rays. The constant properties during a single drop are, e.g., the powers, delays, and directions of the rays.

// Vienna simulator (Single drop & Mobility)
Single drop
Large scale parameters / Small scale parameters are computed only when UE enters a new cube
Within a cube, slight changes in Doppler effect, AoA, and AoD
UE speed = 30km/h = 8.3m/s
-> To move one face to another, it took 1/8.3~20ms
-> Quite long simulation time is required. Or, coherence cube should be small.
Thank you,
