چکیده

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 modiied 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.

Rls-based Initialization for per Tone Equalizers in Dmt-receivers Rls-based Initialization for per Tone Equalizers in Dmt-receivers

Per tone equalization has been proposed in 6] 7] as an alternative to time domain equalization for DMT-based systems. In this paper, an iterative initialization scheme based on so-called RLS with inverse updating is presented for these equalizers. Simulation results show convergence with an acceptably small number of training symbols. Complexity calculations are made for per tone equalization a...

Per tone equalization for DMT-based systems

An alternative receiver structure is presented for discrete multitone-based systems. The usual structure consisting of a (real) time-domain equalizer in combination with a (complex) 1-tap frequency-domain equalizer (FEQ) per tone, is modified into a structure with a (complex) multitap FEQ per tone. By solving a minimum mean-square-error problem, the signal-to-noise ratio is maximized for each i...

Per tone echo cancellation for DMT-based systems

A new echo canceller for discrete multitone (DMT) systems is presented where each used tone has its own per tone echo canceller (PT-EC) in addition to a per tone equalizer (PTEQ) [1, 2]. This enables us to optimize the Signal-to-Noise Ratio (SNR) for each tone separately by solving a Minimum Mean Square Error (MMSE) problem for each tone. Simulation results confirm improved performance over tim...

Combining raised cosine windowing and per tone equalization for RFI mitigation in DMT receivers

Discrete multitone (DMT) offers an elegant way to achieve high capacity, dividing the spectrum into small bands and processing these individually. The per tone equalizer (PTEQ) optimizes the capacity for each band individually, thus optimizing the whole. However, it provides little protection against narrow band radio frequency interference (RFI), being spread over all tones because of the high...
