Abstract: front page image
(EN)This invention relates to a portable information terminal having a function to receive digital broadcasts. Information of Doppler frequency is estimated from received waves. A traveling speed is estimated on the basis of the estimated information of Doppler frequency. A parameter of FFT window is determined in accordance with the estimated traveling speed.
(FR)Cette invention concerne un terminal d'informations portable ayant une fonction de réception de diffusions numériques. Des informations de fréquence Doppler sont estimées à partir d'ondes reçues. Une vitesse de déplacement est estimée sur la base des informations de fréquence Doppler estimées. Un paramètre de fenêtre FFT est déterminé en fonction de la vitesse de déplacement estimée.
(JA) デジタル放送を受信する機能を有する可搬型情報端末。受信波からドップラー周波数の情報を推定し、推定したドップラー周波数の情報に基づいて移動速度を推定し、推定した移動速度に応じてFFTウィンドウのパラメータを決定する。
