A communications device and a data receiving method thereof are provided. The communications device includes: a receiver antenna receiving data; a receiver phase shifter forming a first sum beam and a first difference beam based on a first estimated direction-of-arrival (DOA); a receiver radio frequency (RF) chain generating first difference beam output using the first difference beam formed during a first data period of the received data and generating first sum beam output using the first sum beam formed in a second data period of the received data, which is different from the first data period; and a receiver controller calculating an offset vector between an actual DOA and the first estimated DOA based on the first difference beam output and the first sum beam output. 提供了一种通信装置及其数据接收方法。所述通信装置包括：接收器天线，接收数据；接收器移相器，基于第一估计到达方向(DOA)形成第一和波束以及第一差波束；接收器射频(RF)链，通过将第一差波束应用于接收的数据的第一数据时间段来产生第一差波束输出，并且通过将第一和波束应用于接收的数据的第二数据时间段来产生第一和波束输出，其中，第二数据时间段与第一数据时间段不同；以及接收器控制器，基于第一差波束输出以及第一和波束输出来计算实际DOA与第一估计DOA之间的偏移矢量。
