While optimizing the exit velocity distribution, the constraint optimization algorithm used in this work enforced a limit on the maximum allowable pressure drop in the die; according to this constraint we can control the pressure in the die.
The performance of our method is compared with an existing near capacity method in [9], which employs IrVLC for the optimization of EXIT curves.
The optimization of exit diameter of a cold spray nozzle under different spray conditions was investigated numerically for the first time.
With the same initial degree allocations and ϵ settings, EBSA was performed for SNR = 3.1 dB. Figure 7 show with and without optimization the EXIT curves for SNR = 0.8 dB and 3.1 dB, respectively, for SI-BICM-ID-EM.
In order to approach the capacity, based on EXIT chart, we propose an optimization method of outer channel codes to match with a given demapper for the JCMD-ID system.
Since our optimization is based on EXIT analysis, to avoid excessive inaccuracy, F should better be low, here no more than 5 is a necessary limit.
Due to the expensive computational cost, the surrogate-based optimization is proposed to search the optimal exit location, which combines the polynomial chaos expansion and genetic algorithm.
The optimal objectives of exhaust hood optimization are the limitation concentration of emission at the exit and the minimum deposition on the exhaust hood walls of cut tobacco.
Taking advantages of the characteristics of mappings discussed in Section 3, we investigate a curve-fitting optimization algorithm of finding an EXIT curve of the irregular doped demapper at a minimum E b /N0, while ensuring that this curve is all above the SISO decoder's inverted EXIT curve and the area within the open EXIT tunnel is as small as possible.
The Euclidean distance spectrum and the EXIT chart are aided for the proposed optimization to provide design guidelines of mappings, and the computational complexity is largely decreased by the classification of mappings.
