Abstract:
An embodiment of the present invention provides a method of improving subcarrier permutation to achieve high frequency diversity of OFDMA systems in wireless networks, comprising introducing different tone selections for different symbols, such that if a channel has only a few tones in each symbol of a resource unit it can still have sufficient frequency diversity.
