Method and a device for transmission with time-frequency mapping of symbols in sub-channels

摘要

A method is provided for mapping data symbols at the input of a multi-carrier modulator, which data symbols are interleaved in blocks of K symbols, into sub-channels of size equal to NSDC consecutive carriers scattered to one or more multi-carrier symbols, NSDC being a sub-multiple of K. The size NSDC of the sub-channels is determined as a function of a symbol interleaving pattern diversity between sub-channels.

1. A method of mapping data symbols at the input of a multi-carrier modulator, which data symbols are interleaved in blocks of K data symbols, into sub-channels, each of size equal to NSDC consecutive carriers scattered to one or more multi-carrier symbols, NSDC being a sub-multiple of the number of data symbols per block K, wherein the size NSDC of the sub-channels is determined as a function of a data symbol interleaving pattern diversity evaluated by a geometrical diversity criterion that includes quantifying interleaving dispersion within a sub-channel and between sub-channels.
