Given the sampled data of each element, the signal processing of AAA consists of three parts: the determination of source number, the DOA (Direction of Arrival) multi-user detection and DBF (Digital Beamforming).

• 在给定各阵元的取样数据后,自适应阵列天线信号处理的问题一般可以归结到三个方面:信号源数目的确定、波达方向(DOA: Direction of Arrival)的多用户检测和数字波束形成(DBF: Digital Beamforming)。
