Description
送信待ち符号ストリームの中の各連続n個符号と前記パルス波形を所定の演算方法で演算し、符号と前記パルス波形の関連信号を生成する。
畳み込み計算式
乗法計算式
演算ユニットは、送信待ち符号ストリームの中の各連続n個符号と前記パルス波形を所定の演算方法で演算し、符号と前記パルス波形の関連信号を生成することに使われる。
まず、ナイキストシステムは、スペクトル効率を損失することが最大の欠陥である。いかなる物理的に実現できるパルス波形でも、ナイキスト準則を満足するために、過剰な帯域幅を導入せざるを得ず、スペクトル効率を下げてしまう。

ステップS701では、送信信号のパルス波形を生成する。前記パルス波形の広さは
図9は、本発明の第三実施例により提供される信号変調装置の構成概略図である。詳細は下記通り、
本発明の実施例の前記信号変調装置は、下記を含み、
パルス波形生成ユニット901は、送信信号のパルス波形を生成することに使われる。前記パルス波形の広さは
演算ユニット902は、送信待ち符号ストリームの中の各連続n個符号と前記パルス波形を所定の演算方法で演算し、符号と前記パルス波形の関連信号を生成することに使われる;
