Abstract: A radio communication apparatus includes a plurality of antennas, a radio transmission unit configured to execute radio transmission processing on data to be transmitted from the plurality of antennas, and a processor connected to the radio transmission unit. The processor executes a process including acquiring beam group specification information that specifies a beam group that is capable of being formed when the data to be transmitted is transmitted, forming at least one beam included in the beam group, and correcting an envelope of a beam group using correction factors, the beam group including the at least one beam formed, the correction factors corresponding to the beam group specification information.

Abstract: A wireless apparatus includes a plurality of amplifiers coupled in series with each other and a processor coupled to the plurality of amplifiers and configured to: execute an outputting process to cause at least one of the plurality of amplifiers to operate in a way that length of duration in which the at least one of the plurality of amplifiers is set in on state or off state is different from at least one amplifier among rest of the plurality of amplifiers; execute a measurement process to measure power of a signal outputted from an amplifier at the last stage from among the plurality of amplifiers; and execute a decision process to decide a failure of each of the plurality of amplifiers based on a change amount of the power measured by the measurement process at each of the plurality of output timings.

Abstract: A wireless communication performance test method for testing a performance of a wireless processor which is arranged in a wireless transmission device for performing a transmission and reception operation of a wireless signal, includes operations of transmitting, performing, and measuring. The operation of transmitting is for transmitting, to the wireless processor, a wireless signal including control information for controlling the transmission and reception operation performed by the wireless processor from a wireless transmission test use measurement device for measuring a wireless transmission performance of the wireless processor. The operation of performing is for performing the transmission and reception operation in the wireless processor based on the control information extracted from the wireless signal transmitted from the wireless transmission test use measurement device.
