Title (EN) INTER-CARRIER INTERFERENCE COMPENSATION
(FR) COMPENSATION D'INTERFÉRENCE ENTRE PORTEUSES
Abstract:
(EN) An inter-carrier interference method comprises: receiving one or more OFDM signal comprising plural blocks of OFDM subcarriers of a first type and plural blocks of OFDM subcarriers of a second type, wherein the frequencies of the subcarriers of each block of OFDM subcarriers of the first type are contiguous and wherein the plural blocks of subcarriers of the first type are distributed amongst the plural blocks of subcarriers of the second type; for each of the plural blocks of subcarriers of the first type, estimating inter-carrier interference components;estimating inter-carrier interference components for the subcarriers of the second type using the inter-carrier interference components estimated for the plural blocks of subcarriers of the first type; and compensating for inter-carrier interference in the plural blocks of subcarriers of the second type using the inter-carrier interference components estimated for the subcarriers of the second type, thereby to generate plural compensated blocks of subcarriers of the second type.
(FR) Un procédé d'interférence inter-porteuses consiste à : recevoir un ou plusieurs signaux OFDM comprenant plusieurs blocs de sous-porteuses OFDM d'un premier type et plusieurs blocs de sous-porteuses OFDM d'un second type, les fréquences des sous-porteuses de chaque bloc de sous-porteuses OFDM du premier type étant contiguës et les multiples blocs de sous-porteuses du premier type étant répartis parmi les multiples blocs de sous-porteuses du second type; pour chacun de la pluralité de blocs de sous-porteuses du premier type, estimer des composantes d'interférence inter-porteuses; estimer des composantes d'interférence inter-porteuses pour les sous-porteuses du second type à l'aide des composantes d'interférence inter-porteuses estimées pour les multiples blocs de sous-porteuses du premier type; et compenser l'interférence inter-porteuses dans les multiples blocs de sous-porteuses du second type à l'aide des composantes d'interférence inter-porteuses estimées pour les sous-porteuses du second type, pour ainsi générer plusieurs blocs compensés de sous-porteuses du second type.
