Abstract

See full text

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 sub-carriers of the second type, thereby to generate plural compensated blocks of subcarriers of the second type.
