Abstract
(EN)
A wireless transmission device (2) is characterized by being provided with a repetition encoding unit which prepares a basic waveform with a length less than a frequency conversion length used in a wireless reception device, generates a repetition waveform in which the basic waveform is repeated a plurality of times and which has a length greater than or equal to the frequency conversion length, and generates a data frame including the repetition waveform and a known signal.
(FR)
Un dispositif de transmission sans fil (2) est caractérisé en ce qu'il est pourvu d'une unité de codage de répétition qui prépare une forme d'onde de base ayant une longueur inférieure à une longueur de conversion de fréquence utilisée dans un dispositif de réception sans fil, génère une forme d'onde de répétition dans laquelle la forme d'onde de base est répétée une pluralité de fois et qui a une longueur supérieure ou égale à la longueur de conversion de fréquence, et génère une trame de données comprenant la forme d'onde de répétition et un signal connu.
(JA)
無線送信装置(2)は、無線受信装置で使用される周波数変換長未満の長さの基本波形を準備し、基本波形を複数回繰り返した周波数変換長以上の長さの繰返し波形を生成し、繰返し波形および既知信号を含むデータフレームを生成する繰返し符号化部と、を備えることを特徴とする。
