用于多用户无线通信的相位旋转制造技术

公开了一种用于减轻多用户无线通信环境中用户间干扰的机制。第一网络设备为与该第一网络设备相关联的多个目的设备中的每一个目的设备确定与对应多个副载波相关联的多个引导矩阵。确定与这些目的设备中的每一个目的设备相关联的多个引导矩阵的每一对连贯引导矩阵的对应引导向量之间的相位差，并执行相位旋转以维持连贯引导矩阵之间的相位连续性。至少基于多个引导矩阵的与这多个目的设备相关联的子集来计算一个或多个预编码矩阵。向要传送给这多个目的设备的数据应用这一个或多个预编码矩阵以减轻这多个目的设备中的每一个目的设备之间的干扰。

Phase rotation for multi-user wireless communications

Disclosed is a mechanism for mitigating inter user interference in multi-user wireless communication environments. The first network device determines a plurality of boot matrices associated with a plurality of subcarriers in each of the plurality of destination devices associated with the first network device. Objective to determine with these devices in each destination device associated with a plurality of guide matrices each of the matrix corresponding to the phase coherence guide vector difference between, and perform phase rotation to maintain coherence guided phase continuity matrix. One or more precoding matrices are calculated based on at least a subset associated with the plurality of destination devices based on a plurality of boot matrices. The application of one or more precoding matrices to data to be transmitted to a plurality of destination devices to mitigate interference between each of the plurality of destination devices.
