摘要：

The specifications of filter banks for multicarrier transmission systems with a large number of subchannels are discussed, with application to xDSL and power line communication in mind. The near PR modulated approach is considered and the importance, for the system, of the protype filter delay is stressed. An existing design technique known to be particularly relevant to the context is revisited from a frequency sampling perspective. The performance results in terms of subchannel noise floor and delaya re givenf or several filter lengths and an experimental validation isp rovided. Finally, an improvement to the design technique is proposed, which brings a gain of 3.3 dB in subchannel interference power level.
