Title:
周波数分割多重伝送信号受信装置
Document Type and Number:
Japanese Patent JP5398284
Kind Code:
B2
Abstract:
A frequency division multiplex transmission signal receiving apparatus for receiving a frequency division multiplex transmission signal using a plurality of carries includes: an estimation section estimating a transfer function of a received signal after the received signal has been transformed into a frequency domain signal; a demodulation section demodulating the received signal according to the transfer function estimated by the estimation section; a plurality of variation detecting sections performing variation detection using a plurality of different variation detection methods, based on the transfer function estimated by the estimation section; a reliability determining section determining reliability based on a result of a combination of variation detection results of the plurality of variation detecting sections; and a correction section performing error correction of the demodulated signal from the demodulation section, the demodulated signal being subjected to an application of a reliability determination result of the reliability determining section.
