Abstract
This paper presents a subband filter bank model of N subbands for orthogonally multiplexed QAM system with 2N subchannels. Then, a fast implementation algorithm using polyphase decomposition and discrete cosine transform (DCT) is derived from this model. Compared with the implementation method through discrete Fourier transform, only half the computation cost is needed. Finally, we give the adaptive equalization scheme based on subband adaptive filter theory, and its efficiency is verified by experiments
