Abstract

　より正確なチャネル推定値の算出を可能とする新規のパイロット送信方法、当該パイロット送信方法を用いるＭＩＭＯ送信装置、及び当該ＭＩＭＯ送信装置と通信を行うＭＩＭＯ受信装置。ＭＩＭＯ送信装置（１００）では、巡回シフト処理部（１５０）が、拡散符号１で拡散された第１のパイロット信号系列と拡散符号２で拡散された第２のパイロット信号系列とを、異なるシフト量でそれぞれ巡回シフトする。そして、巡回シフトされた第１のパイロット信号系列及び第２のパイロット信号系列が、異なる送信アンテナから同一のパイロット送信シンボル区間で送信される。こうして別々の拡散符号で拡散された各パイロット信号系列に施される巡回シフト処理のシフト量を変えることにより、受信側でパイロットの分離精度を向上することができる。この結果、より正確なチャネル推定値の算出が可能となる。
