Abstract:
A method for arranging distributed sub-channels in a multicarrier transmission system is provided to improve transmission diversity efficiency by using two sub-carriers or symbols as a single basic unit. Two neighboring carriers, which are adjacent to each other on a frequency axis, are grouped into a single basic unit, and the basic units are distributed on a channel in a multicarrier transmission system. The channel is arranged, such that the basic units are adjacent each other on the frequency axis, while the basic units are apart from each other by a distance greater than one symbol interval on a time axis. Alternatively, two symbol intervals, which are adjacent to each other on the time axis, are grouped to form the single basic unit.
