使用dma_alloc_coherent申请了一块内存,然后使用mmap映射到用户空间。然后,我用千兆网卡(CPSW驱动)进行发送(UDP方式),测量到的速度仅有12.5MB/s。 我又另外做了一个测试

此技术文章说明了LabVIEW 与USRP 平台的使用方式,进而打造出相位同调(Phase Coherent) 的MIMO 测试台,可以从2x2 扩充为8x8 天线设定,并且用来测试多种MIMO 与多用户的通信研究项目。

(Propagation) 功能。此外,目前有多款 RADAR 系统均使用电磁波束控制 (Beam steering),以取代传统的机械控制传输讯号。这些应用均属于多通道相位同调 (Phase coherent) RF
