This agrees with the analysis in Section 5 that an imbalance allocation of data subcarriers in the unconstrained system results in a reduced average MSE, as well as a reduced average SNDR, compared to that in the proposed system.
An imbalance in allocation of workforce favors urban areas and is exacerbated by internal migration and absenteeism in rural healthcare facilities [ 14].
As the result, the effect of imbalance allocation is assumed to be reduced by the local memory access.
It is obvious that the imbalance allocation of data subcarriers associated with the conventional per-subcarrier antenna selection scheme reduces the potential benefits of the antenna selection OFDM systems.
To illustrate the impacts of nonlinear distortions due to nonlinear HPAs on transmitted data symbols in the antenna selection OFDM system, we plot in Figure 2 the constellation diagrams of 16-QAM symbols in two scenarios: imbalance allocation and balance allocation of data subcarriers.
In addition, the imbalance allocation of the data subcarriers on antennas can lead to noncausality as discussed in Section 3. It is intuitive that these problems can be avoided if the same number of data subcarriers is allocated to all transmit antennas, as illustrated in Figure 3.
Before making a positive answer to this problem, we need to address the following challenge, i.e., users have to make their balancing decisions with only very limited and dynamic local load information, which could possibly incur longer convergence time and imbalanced task allocations.
But Lamb said that in the UK and elsewhere there was an imbalance of resource allocation between mental and physical health.
Possibly, the rotation of T1 within Taatgen and colleagues' blocked design may have led to an imbalance in the allocation of attention, inducing an additional cost for T2, which is not the case when both targets are rotated (as shown in the present study).
