Abstract

　ハンドオーバなどの通信処理を高速かつ高品質に実現することができる通信装置および通信方法を提供することを目的とする。 　移動通信用端末１０１は、通信部１０２ａで受信された受信信号が所定値以下になったと電力測定部１０５において判断された場合、周波数変換部１０２ｂ（ＦＦＴ演算器８）は、受信される受信信号に対して時間・周波数変換（例えば、ＦＦＴまたはＤＦＴ）を行うための周波数範囲を拡大して演算を行う。そして、周波数測定部１０２ｃ（検出回路９）は、拡大された周波数範囲内の受信信号の受信強度を測定し、測定された信号のうち、予め定めた受信強度より高い信号の周波数を検出し、通信部１０２ａはその周波数の信号を用いて接続処理を実行する。
