摘要:
A dual path equalization structure is used to equalize DMT systems operating over channels in which different impairments dominate the performance of different parts of the channel. Two TEQ/DFT structures are used to process the received signal, each optimized for a different part of the channel. The outputs of the two paths are combined with appropriate frequency-domain equalization to achieve an overall equalization architecture which is better optimized for the whole channel.
