PROBLEM TO BE SOLVED: To provide a novel and improved method and apparatus for generating a reduced peak amplitude high data rate channel comprising a set of lower rate channels. SOLUTION: There is provided an apparatus and a method for carrying out data transfer at a high data rate in a plurality of low data rate channel. The set of lower rate channels are phase, rotated before being summed and transmitted. The amount of phase rotation is dependent on the number of channels used to form the higher rate channel. In one embodiment where two lower rate channels are used, the in-phase and quadrature-phase components of the two channels are complex multiplied before upconversion with an in-phase and quadrature-phase sinusoids. For a high rate channel comprising more than two lower rate channels, the in-phase and quadrature-phase component of each channel is upconverted with a set of sinusoids that are phase offset from one another.
