Abstract
(EN)
Provided is a radio communication device capable of preventing lowering of the frequency diversity effect when using the CDD (Cyclic Delay Diversity) in combination with the frequency diversity technique in a multi-carrier communication. In the radio communication device (100), a repetition unit (103) repeats each symbol to generate the same symbol, an S/P unit (104) converts a symbol string inputted in series from the repetition unit (103) into a parallel string, and an arrangement unit (105) arranges a plurality of symbols inputted in parallel to any of a plurality of sub-carriers constituting the OFDM symbol. Here, the arrangement unit (105) correlates a plurality of the same symbols generated by repetition to a cyclic delay in the CDD and arranges them to any of the sub-carries constituting each of the OFDM symbols at a sub-carrier interval based on the number of antennas and the delay amount of the CDD transmission.

L'invention concerne un dispositif de communication radio apte à prévenir un affaiblissement de l'effet de diversité de fréquence lors de l'utilisation de la diversité à retard cyclique (CDD) en combinaison avec la technique de diversité de fréquence dans une communication multi-porteuse. Dans ce dispositif de communication radio (100), une unité de répétition (103) répète chaque symbole pour générer un symbole identique, une unité S/P (104) convertit une chaîne de symboles entrés en série par l'unité de répétition (103) en une chaîne parallèle, et une unité de disposition (105) arrange une pluralité de symboles entrés en parallèle par rapport à une sous-porteuse quelconque parmi une pluralité de sous-porteuses constituant le symbole OFDM. L'unité de disposition (105) met en corrélation une pluralité de symboles identiques générés par répétition avec un retard cyclique de CDD et elle les dispose par rapport à une sous-porteuse quelconque constituant chacun des symboles OFDM à un intervalle de sous-porteuse basé sur le nombre d'antennes et sur la quantité de retard de la transmission CDD.

 マルチキャリア通信においてCDD(Cyclic Delay Diversity)および周波数ダイバーシチ技術の双方を組み合わせて用いる場合に、周波数ダイバーシチ効果の滅却を防ぐことができる無線通信装置。この無線通信装置(100)において、レピティション部(103)は各シンボルを複製(レピティション)して複数の同一シンボルを生成し、S/P部(104)はレピティション部(103)から直列に入力されるシンボル列を並列に変換し、配置部(105)は、並列に入力される複数のシンボルを、OFDMシンボルを構成する複数のサブキャリアのいずれかに配置する。この際、配置部(105)は、レピティションにより生成された複数の同一シンボルを、CDDでの循環遅延に対応させて、複数のアンテナの数とCDD送信の遅延量とに応じたサブキャリア間隔にて各OFDMシンボルを構成する複数のサブキャリアのいずれかに配置する。
