Besides, the instantaneous knowledge of all links and average knowledge of the eavesdropper links are considered in [19].
Motivated by the transmission of training sequences, it is assumed that each receiver has perfect instantaneous knowledge about its own channel gain, which is an acceptable assumption for block fading networks[42 47].
Numerous studies have demonstrated adaptive behavioral responses of males and females to changes in operational sex ratio (the ratio of potentially receptive males to receptive females; OSR), and theory often assumes that animals have perfect instantaneous knowledge about the OSR.
To provide an upper bound on the performance of reconfigurable antennas in ad hoc networks, we consider the use of a powerful centralized controller that has instantaneous knowledge of all communication and interference channels ( e. g., H l r c, i t c, ∀ l, i ∈ ℒ ).
We concentrate on what is known as the waterfilling-in-time strategy, since it is the optimal solution with respect to capacity optimization under an average transmit power constraint when both the AP and the mobile user have perfect and instantaneous knowledge of channel conditions [21].
