Digital Modulation Techniques, Second Edition

本書は、今日の通信で使われているディジタル変調技術に関する最も理解しやすい手引き書として改訂されています。同期化、フェーディングチャンネルの性能、チャンネルの評価と等化、ピーク対平均の電力低減技術、OFDMに基づいたnon-FFTなどを含む、OFDMに関する五つの新しい章が提供されています。第二版では光通信用の新しい変調技術とM-ary ASK信号、パルス整形、チャンネル評価やダイバーシティ技術のような緩和方法についてもカバーされています。また、操作原理、ビット誤りの生起可能性、スペクトラル特性、変調装置、復調装置、シンクロナイザ、他の技術との比較やアプリケーションについても詳細に書かれています。本書で学習することにより、実装ダイアグラムやビット誤りのようなデータ、また与えられたデータレートで用いられる各方式の占有帯域幅を簡単に見つけられるようになるので、変調方式の公式化や、アプリケーションの最適方式の決定を確信を持って行えるようになります。
