摘要：
An alternative receiver structure is presented for discrete multitone (DMT)-based systems. The usual structure consisting of a (real) time domain equalizer (TEQ) with a (complex) 1-taps frequency domain equalizer (FEQ) per tone, is modified into a structure with a (complex) multitaps FEQ per tone. By solving an MMSE problem, the SNR is maximized for each tone separately. This always results in a larger bitrate while complexity during data transmission is kept at the same level. Moreover, the per tone equalization is shown to have a reduced sensitivity to the synchronization delay.
