    Abstract: A millimeter-wave controller receives, from a microwave-communication control apparatus belonging to a microwave network, a first signal including location information of a first terminal belonging thereto and a use request for the first terminal to use the millimeter-wave network. A beam range for the first terminal and a first wireless resource that is included in one or more wireless resources of one or more millimeter-wave access points and that is to be allocated to the first terminal are set based on the location information. A use permission for the millimeter-wave network and first connection information for connection to a first millimeter-wave access point corresponding to the first wireless resource are transmitted to the microwave-communication control apparatus. The first connection information differs from second connection information for a second terminal belonging to the millimeter-wave network, the second terminal connects to the first millimeter-wave access point by using the second connection information.

    Abstract: A distortion-compensating power amplifier compensates for nonlinear distortion in a power amplifier. The distortion-compensating power amplifier includes: a predistorter that performs pre-distortion processing, the pre-distortion processing applying an inverse characteristic of a distortion characteristic that is generated in the power amplifier to an input signal; a filter that performs band limitation on the pre-distorted input signal by using a frequency characteristic that is asymmetric with respect to a center frequency of the input signal, the filter having a filter coefficient that is a complex number; a down-sampler that down-samples the band-limited input signal; and a digital-to-analog converter that converts the down-sampled input signal from a digital signal to an analog signal.
