Abstract: Provided is a communication system for transmitting data using a plurality of interference-free communication channels. A transmission apparatus may inactivate a portion from among a plurality of transmit antennas and thereby group transmit antennas into a plurality of antenna groups. A channel formed between each antenna group and a reception apparatus may have a relatively low correlation and thus, the may be assumed to be independent. Accordingly, the transmission apparatus and the reception apparatus may transmit data using separate interference-free communication channels.
Abstract translation: 提供了一种用于使用多个无干扰通信信道发送数据的通信系统。 发送装置可以使多个发送天线中的一部分失活，从而将发送天线分组成多个天线组。 在每个天线组和接收装置之间形成的信道可以具有相对低的相关性，并且因此可以假定为独立的。 因此，发送装置和接收装置可以使用分离的无干扰通信信道来发送数据。
