"Efisiensi penggunaan sumber daya spektrum frekuensi yang terbatas merupakan target utama dari sistem komunikasi nirkabel. Keterbatasan spektrum frekuensi ini, telah mendorong para peneliti untuk mengembangkan komunikasi nirkabel full-duplex. Pada penelitian ini penulis mengusulkan skema optimasi penggunaan daya pada kanal MIMO full-duplex yang telah dilengkapi dengan teknik selfinterference cancellation pada domain propagasi.
Pada penelitian ini diturunkan dan dianalisis persamaan mencari daya optimum dari sebuah kanal MIMO fullduplex yang akan menghasilkan kapasitas maksimum dengan menggunakan metode optimasi konveks. Berdasarkan hasil perhitungan terhadap kanal yang telah dioptimasi dapat dibuktikan bahwa kapasitas kanal meningkat sebesar 9 % pada penggunaan daya total sebesar 4 dB dan N=4 dibandingkan kapasitas kanal tanpa optimasi.

Improving spectral efficiency driven by the limited frequency resources is a key target of the wireless communication system. The limitation of the frequency spectrum has led researchers to develop a full-duplex wireless communication. In this research, author proposes a power optimization scheme of full-duplex MIMO channel that has been equipped with self-interference cancellation techniques in the propagation domain.
In this research, by using convex optimization method, the expression of the optimum power scheme to achieve the maximum capacity of full-duplex MIMO channel is derived and analyzed. Calculation result shows that the capacity of the optimized channel increase 9 % at the total power 4 dB and N=4 compare with channel without optimization.

"Recent developments in model-predictive control promise remarkable opportunities for designing multi-input, multi-output control systems and improving the control of single-input, single-output systems. This volume provides a definitive survey of the latest model-predictive control methods available to engineers and scientists today.
The initial set of chapters present various methods for managing uncertainty in systems, including stochastic model-predictive control. With the advent of affordable and fast computation, control engineers now need to think about using “computationally intensive controls,” so the second part of this book addresses the solution of optimization problems in “real” time for model-predictive control. The theory and applications of control theory often influence each other, so the last section of Handbook of Model Predictive Control rounds out the book with representative applications to automobiles, healthcare, robotics, and finance.
The chapters in this volume will be useful to working engineers, scientists, and mathematicians, as well as students and faculty interested in the progression of control theory. Future developments in MPC will no doubt build from concepts demonstrated in this book and anyone with an interest in MPC will find fruitful information and suggestions for additional reading."
