摘要

自干扰信道状态信息（CSI）的估计是全双工模拟相控阵的一个重大挑战。提出了一种基于SI功率反馈的SI通道矩阵与其共轭转置矩阵乘积的估计方法，而不是收集CSI。CHP估计可以在交通时隙中完成，几乎不需要额外的专用时隙。因此，可以及时跟踪信道的变化。在此基础上，给出了一种低复杂度的最优发射波束形成（TxBF）权值求解方法。仿真是基于硬件原型试验台的实际SI通道测量。结果验证了热电联产估计和TxBF优化方法的有效性。

Self-Interference Channel Hermitian Product Estimation Based on Power Feedback in Full-Duplex Phased Arrays

The estimation of self-interference (SI) channel state information (CSI) is a significant challenge for full-duplex analog phased arrays. Instead of collecting CSI, an SI channel Hermitian product (CHP) estimation method is proposed to estimate the product of the SI channel matrix and its conjugate transpose matrix based on SI power feedback. CHP estimation can be accomplished in traffic time slots with little need for additional dedicated time slots. Hence, channel changes can be tracked in time. Furthermore, a low-complexity solution for the optimal transmit beamforming (TxBF) weight is provided on the basis of CHP estimation results. Simulations are based on actual SI channel measurements from a hardware prototype testbed. The results verify the effectiveness of the CHP estimation and TxBF optimization methods.

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
