RECEPTION DEVICE, RECEPTION METHOD, AND RECEPTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent the increase of computational complexity when detecting information from a received signal under a high speed fading environment where a delay path exists. SOLUTION: A propagation channel estimation unit b106 estimates a propagation channel estimation value. A symbol replica generation unit b110 generates symbol replicas, which are modulated symbols from demodulated information. On the basis of the propagation channel estimation value and symbol replicas, a signal extraction unit B1 extracts each subcarrier component from a received signal from which interference has been removed. A demodulation unit b108 demodulates a signal having the subcarrier components extracted by the signal extraction unit B1. COPYRIGHT: (C)2011,JPO&INPIT
