Abstract
A radio transmitting station includes: multiple transmitting antenna elements configured to transform electrical signals into radio waves and emit the radio waves; a precoder configured to control a beam direction of the radio waves to be emitted from the multiple transmitting antenna elements by giving precoding weights to the electrical signals to be supplied to the multiple transmitting antenna elements; and at least one power adjuster configured to adjust power of an electrical signal that is to be supplied to at least a portion of the multiple transmitting antenna elements, such that differences between powers of the electrical signals to be supplied to the multiple transmitting antenna elements are reduced.
