摘　　要：A Non-Uniform Discrete-Multitone(DMT) transceiver can help mitigate the channel-noise enhancement,attributed to zero-forcing equalization (ZFE) technique,by splitting the channel frequency response into octave spaced subbands.This paper presents a novel quantitative analys is of the channel-noise enhancement in different subbands of the Non-Uniform DMT system.In order to improve the bit error rate(BER) performance,a modified Non-Uniform DMT transceiver is proposed.The BER performance of the modified Non-Uniform DMT system is compared with that of the Non-Uniform DMT and conventional DMT systems in a Digital Subscriber Line(DSL).A Non-Uniform Discrete-Multitone(DMT) transceiver can help mitigate the channel-noise enhancement,attributed to zero-forcing equalization (ZFE) technique,by splitting the channel frequency response into octave spaced subbands.This paper presents a novel quantitative analys is of the channel-noise enhancement in different subbands of the Non-Uniform DMT system.In order to improve the bit error rate(BER) performance,a modified Non-Uniform DMT transceiver is proposed.The BER performance of the modified Non-Uniform DMT system is compared with that of the Non-Uniform DMT and conventional DMT systems in a Digital Subscriber Line(DSL).
