Abstract
Embodiments of transmission data stream pre-processing are disclosed. A method includes receiving the data stream for transmission, forming blocks of samples from the data stream, inverse Fourier transforming the blocks of samples forming multi-carrier signal symbols, selecting sets of k multi-carrier signal symbols and time expanding each of the sets of the k multi-carrier signal symbols into sets of n multi-carrier signal symbols, where n is greater than k, and transmitting each of the n multi-carrier signal symbols. The time expansion can be accomplished by coding the coding the sets of k multi-carrier signal symbols.
