论文摘要
在这项工作中，我们研究了具有不完美光束成形的全双工高斯1-2-1网络的能力。特别是，与[1]中引入的理想1-2-1网络模型不同，在此模型时光形式的模式会导致侧室泄漏，无法完全抑制。 1-2-1网络模型捕获了MMWave网络通信的方向性，在该方向上通过将主型“横梁”指向对方来通信。我们表征了相同通道系数的不完善能力和理想1-2-1模型的近似能力和传输功率之间的差距。我们表明，在某些情况下，此差距仅取决于节点的数量。此外，我们评估了将最终的侧室泄漏视为噪声的方案的可实现速率，并证明它们为实施提供了合适的解决方案。
In this work, we study bounds on the capacity of full-duplex Gaussian 1-2-1 networks with imperfect beamforming. In particular, different from the ideal 1-2-1 network model introduced in [1], in this model beamforming patterns result in side-lobe leakage that cannot be perfectly suppressed. The 1-2-1 network model captures the directivity of mmWave network communications, where nodes communicate by pointing main-lobe "beams" at each other. We characterize the gap between the approximate capacities of the imperfect and ideal 1-2-1 models for the same channel coefficients and transmit power. We show that, under some conditions, this gap only depends on the number of nodes. Moreover, we evaluate the achievable rate of schemes that treat the resulting side-lobe leakage as noise, and show that they offer suitable solutions for implementation.
