提出了一种具有4个异构核的2.2 mm2全数字基带SoC，用于128节点8用户分布式大规模MIMO。两个专用dsp在0.1ms内执行快速空中同步。高度优化的8复杂通道MIMO矢量处理器比通用处理器提供4倍的硬件效率提高。电路优化和体偏置的使用导致在169 Mb/s的检测速率下测量能量为1070 pJ/b。
A 2.2 mm2 full digital baseband SoC with four heterogeneous cores for 128-node 8-users distributed massive MIMO is presented. Two specialized DSPs perform rapid over-the-air synchronization within 0.1ms. A highly optimized 8-complex lane MIMO vector processor provides 4x hardware efficiency improvement over general-purpose processors. Circuit optimizations and the use of body-bias result in 1070 pJ/b measured energy at 169 Mb/s detection rate.
