Relation between Channel InitTime and Coherence Time of Channel

Hi,

In MATLAB, in almost all the channel models, there is a configurable parameter named InitTime.

Documentation says: Fading process time offset, in seconds.

I want to generate a scenario where I want to see the effect of same channel on the same packet but at different instances of time. Basically I want to see how the channel changes over time for a given coherence time. Let's assume the coherence time is 4 sec.

Now if my packet is P and the channel is C whose InitTime I set as

C.InitTime = 3

then step(C, P) to get the output P3

Now I again set the same channel (with changing any other parameter)

C.InitTime = 10

then step(C, P) to get the output P10

With this can I expect that channel effect on P3 and P10 will be uncorrelated because the offset of 7 sec is more than the channel coherence time of 4 sec.

Can someone comment if I am using the parameter correctly.

Thanks & Regards
