…In contrast, the normal reception method is called single reception. There are many methods used to obtain signals with little correlation, including spatial diversity, which uses multiple receiving antennas spaced apart by several wavelengths, polarization diversity, which receives multiple differently polarized waves, frequency diversity, which uses multiple transmission channels in different frequency bands, and time diversity, which transmits signals multiple times with a certain time lag. [Yoshiaki Hayashi] … *Some of the terminology explanations that refer to "spatial diversity" are listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
…これに対して通常の受信方式を単一受信single receptionという。 相関の少ない信号を得る方法として,互いに数波長隔たった複数の受信アンテナで受信する空間ダイバーシティ,複数の異なった偏波を受信するようにした偏波ダイバーシティ,異なった周波数帯域の送信チャンネルを複数個用いて送信する周波数ダイバーシティ,信号伝送を一定時間ずらして複数回行う時間ダイバーシティなど多種類のものが用いられている。【林 義昭】。… ※「空間ダイバーシティ」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
