A technique for generating a single carrier frequency division multiple access (SC-FDMA) signal is described, in which from a set of M input symbols a set of N output symbols (M < N) is generated. A method implementation of this technique comprises receiving a set of M input symbols in a time domain representation, subjecting the set of M input symbols to an interpolation operation in the time domain to obtain L interpolated samples (L ‰¤ N), mapping the interpolated symbols, or symbols derived from the interpolated symbols, to N orthogonal sub-carriers, and outputting N output symbols in a time domain representation. |
