A new method of realizing the unequal bandwidth multicarrier modulation

In the traditional multicarrier modulation, the channel is divided into equal-bandwidth subchannels. In order to fit the channel characteristics well, adopting the way of parting the channel unequally is an important development direction of multicarrier modulation. In this paper, we present an algorithm of realizing the parting the channel unequally by using the orthogonal wavelet packet transforms in the multicarrier modulation. The theoretical analyses and the simulation results show that this way has great potential to improve the transmission performance of the channel.
