Document Type and Number:
Japanese Patent JP5318091
Kind Code:
B2
Abstract:
A receiving antenna diversity effect is improved by equalizing the likelihood while exchanging the likelihood among a plurality of equalizers. A receiving apparatus (300) which receives radio signals using a plurality of antennas (301-1 to 301-M), comprises: pilot separation sections (304-1 to 304-M) separating a pilot signal and a received data signal from the radio signals; a channel estimation section (305) calculating a channel estimation value corresponding to each of the antennas (301-1 to 301-M) according to the pilot signal; and a reception processing section (306) performing signal detection for the received data signal corresponding to each of the antennas (301-1 to 301-M) and having a plurality of equalization sections each generating likelihood information according to the received data signal and the channel estimation value, wherein any one of the equalization sections generates likelihood information using the likelihood information generated by another equalization section and also outputs the generated likelihood information to another equalization section.
