摘要:
A wireless transmitter controls the number of transmission beams to be formed for transmitting a data stream depending on the number of data streams to be transmitted, and a wireless receiver selectively receives any one or more of the transmission beam from the transmission beams. In this manner, by changing the number of transmission beams (the original number of beams selectable on the receiving side) to be formed depending on the number of transmitting data streams, high throughput characteristics by a low interbeam correlation at the time of the multistream transmission and a large directional gain at the time of a single stream may be achieved.
