摘要

本文的目的是报告约束随机梯度(CSG)算法在两个事件组合下的不适应波束形成行为:一个或多个干涉到达角接近信号到达角，并且涉及信号的角扩展很小。在这种情况下，CSG算法更强调同信道干扰的最小化，而不是辐射到小区内移动终端的功率的最大化。我们将这种现象称为不平衡行为，并提供一种分析研究来解释它。

On the constrained stochastic gradient algorithm behavior in wireless communication networks

The purpose of this paper is to report on an unsuitable behavior of the constrained stochastic gradient (CSG) algorithm for adaptive beamforming in the combination of two events: one or more interference angles-of-arrival are close to the signal angle-of-arrival and the angle spreads of the involved signals are small. In this situation, the CSG algorithm stresses the co-channel interference minimization more than the maximization of the power radiated to the in-cell mobile terminal. We term this phenomenon unbalanced behavior and provide an analytical study to explain it.
