In this paper, we consider a fundamental problem in modern digital communications known
as multiple-input multiple-output (MIMO) detection, which can be formulated as a complex …

In this paper, we consider a class of nonconvex complex quadratic programming (CQP)
problems, which find a broad spectrum of signal processing applications. By using the polar …

Multiple-input multiple-output (MIMO) detection is a fundamental problem in wireless
communications and it is strongly NP-hard in general. Massive MIMO has been recognized …

In this paper, we propose an effective full array and sparse array adaptive beamforming
scheme that can be applied for multiple desired signals based on the branch-and-bound …

无线通信系统设计中的许多问题可建模为优化问题. 一方面, 这些优化问题常常具有高度的非
线性性, 一般情况下难于求解; 另一方面, 它们又有自身的特殊结构, 例如隐含的凸性, 可分性等 …

Many problems arising from wireless communication system design can be formulated as
optimization problems. On the one hand, these optimization problems are often non-convex …
