This results in a high performance gain of our CARA heuristic.
To achieve high performance, gain tuning is of great importance in PID controllers.
The open-loop multiple-input multiple-output (MIMO) technique has already been shown to achieve a high performance gain.
As μ1 = 0.1 means the user1 is more close to the cell edge, cooperation would lead to higher performance gain.
Optimal beamforming design for MIMO AF relaying scheme achieves high performance gain and higher information rates than MIMO DF and MIMO CF relaying scheme.
Thus, it may introduce very small detection delay, while still providing high performance gain, compared to the constituent ST codes, with low encoding and detection complexity.
With the new method, named as semi-random backoff (SRB), analytical study and simulation results show that SRB performance is better than the default 802.11 DCF/EDCA and can achieve even higher performance gain over default 802.11 DCF/EDCA.
The higher performance gain at larger K or β comes from the fact that more channel directions can be learned and utilized for interference suppression by M-MMSE, while S-MMSE always uses K directions regardless of β.
Therefore, the cooperative decoding for CSI feedback under the bandwidth partitioning provides a higher performance gain than the V-MIMO feedback scheme in the low SNR regime, where (B_{MRC}^{i} = MB_{ZF}^{i}).
Direct comparison of then- and posttest ratings also yielded slightly higher performance gain than sequential ratings, but this effect was negligibly small.
Based on the theoretical considerations outlined above, we derived the following hypotheses: (a) Thentest ratings are less positive than true pretest ratings, thus producing higher performance gain values.
