具有数字可配置的自适应线性化的最小反馈无线电架构
摘要：
本发明涉及具有数字可配置的自适应线性化的最小反馈无线电架构。包括了一种无线电传输系统，该无线电传输系统包括多个功率放大器(PA)；与PA对应的多个Volterra引擎(VE)线性化电路；与PA对应的多个反馈回路；耦合到VE线性化电路的至少一个数字混合矩阵(DHM)；以及耦合到PA的模拟混合矩阵(AHM)，其中所述反馈回路连接到AHM和VE线性化电路但不连接到PA以减少反馈回路的数量。还包括一种无线电系统，该无线电系统包括多个PA；耦合到PA的Volterra DHM(VDHM)；与PA对应的多个反馈回路；以及耦合到PA的AHM，其中反馈回路连接到AHM但不连接到PA以减少反馈回路的数量。
摘要（英）：

The invention relates to a minimum feedback radio architecture with digitally configurable adaptive linearization. Included is a radio transmission system comprising a plurality of power amplifiers (PAs); a plurality of Volterra Engine (VE) linearizers corresponding to the PAs; a plurality of feedback loops corresponding to the PAs; at least one digital hybrid matrix (DHM) coupled to the VE linearizers; and an analog hybrid matrix (AHM) coupled to the PAs, wherein the feedback loops are connected to the AHM and the VE linearizers but not to the PAs to reduce the number of feedback loops. Also included is a radio system comprising a plurality of PAs; a Volterra DHM (VDHM) coupled to the PAs; a plurality of feedback loops corresponding to the PAs; and an AHM coupled to the PAs, wherein the feedback loops are connected to the AHM but not to the PAs to reduce the number of feedback loops.
