Claim Text:
1. A transmission method of operating a transmission apparatus for cancelling inter-carrier interference, the method comprising: in the transmission apparatus: configuring, by a configuration unit, at least one isolated sub-carrier between a first set of sub-carriers and a second set of sub-carriers; determining, by a determination unit, a symbol value of non-zero magnitude on the at least one isolated sub-carrier such that a first inter-carrier interference, resulting from the at least one isolated sub-carrier to the second set of sub-carriers compensates a second inter-carrier interference resulting from the first set of sub-carriers on the second set of sub-carriers, wherein the determined symbol value of non-zero magnitude on the at least one isolated sub-carrier is determined based on a combination of a weighted sum of the data symbols on each of the first set of sub-carriers, and a weighting factor corresponding to each of the sub-carriers being determined by inter sub-carrier interference characteristics; and transmitting, by a transmission unit, the determined symbol value of non-zero magnitude via a plurality of sub-carriers comprising the first set of sub-carriers, the second set of sub-carriers and the at least one isolated sub-carrier, and wherein inter sub-carrier interference characteristics is assumed by the determination unit to be characterized such that the interference coefficient between interfering source sub-carriers and target sub-carriers is inversely proportional to a frequency offset between the interfering source sub-carriers and the target sub-carriers.
