标题： Optimal Signaling of MISO Full-Duplex Two-Way Wireless Channel

摘要： 我们对多输入单输出（MISO）全双工双向信道中的自干扰进行建模，并评估可实现速率区域。 我们通过一组耦合的非凸优化问题来表述可实现速率区域的边界，称为帕累托边界。 我们的主要贡献是解耦并重新表述原始的非凸优化问题为一组凸半定规划问题。 对于MISO全双工双向信道，我们证明波束成形是一种最优的传输策略，可以实现帕累托边界上的任意一点。 此外，我们给出了最优波束成形权重的显式表达式。 在我们的数值例子中，我们量化了所提出的波束成形相对于零强迫波束成形在可实现速率上的增益。 显示英文摘要

摘要： We model the self-interference in a multiple input single output (MISO) full-duplex two-way channel and evaluate the achievable rate region. We formulate the boundary of the achievable rate region termed as the Pareto boundary by a family of coupled, non-convex optimization problems. Our main contribution is decoupling and reformulating the original non-convex optimization problems to a family of convex semidefinite programming problems. For a MISO full-duplex two-way channel, we prove that beamforming is an optimal transmission strategy which can achieve any point on the Pareto boundary. Furthermore, we present a closed-form expression for the optimal beamforming weights. In our numerical examples we quantify gains in the achievable rates of the proposed beamforming over the zero-forcing beamforming.
