Abstract

　広ダイナミックレンジ又は高ＰＡＰＲの信号についても高効率な電力増幅が可能なＭＩＭＯ送信装置。ＭＩＭＯ送信装置（１００）において、増幅器（１５０）は、入力信号を増幅してアンテナ（１７０）に増幅信号を出力する。増幅器（１６０）は、入力信号を増幅してアンテナ（１８０）に増幅信号を出力する。ピーク検出部（１３０）は、第１送信系列の包絡線を検出し、分岐切り替え部（１４０）は、第１送信系列の包絡線検出結果としきい値との比較結果に基づいて、第１送信系列のすべてを増幅器（１５０）に入力するか、又は、第１送信系列の一部を第２送信系列と共に増幅器（１６０）に入力するかを切り替える。この構成により、増幅器の入力信号のピークを小さくすることができるので、増幅器を効率的に使用することができる。この結果、高ＰＡＰＲの信号などについても高効率な電力増幅が可能なＭＩＭＯ送信装置を実現することができる。
