The pathloss is modeled as (phantom {dot {i}!}A_{i} d^{-alpha _{i}}) with i∈{c,d}, where index c indicates the pathloss between a user and the BS and index d gives the pathloss between any two users.
Modified means that pathloss is reduced by 3 dB in comparison to COST 231.
However, the interference induced from PU to SU is assumed to be negligible and channel pathloss is not considered.
Then, according to our approach, there will be distinct categories (with one LOS category and NLOS categories) for the pathloss formula, where pathloss is the negative dB value of link gain (received power divided by transmitted power).
This is also a challenge for modelling shadowing over an area, as the pathloss is correlated in space.
Moreover, since the pathloss is constant for each user, it suffices to determine rate allocation in each slot depending only on short-term fading which is time varying, and thus, unlike pathloss, provides diversity which can be exploited.
However, if the channel effect and pathloss are not considered, such dynamic TP may not be optimal.
In our simulations, we do not consider macroscopic pathloss even though it is considered in the output of the QUADRIGA channel model.
For Dr. Leggett, quantum mechanics at the macroscopic level is still uncertain -- and troubling.
The macroscopic behavior is similar to ferromagnetism.
