Discrete Multi-Tone Asymmetric Digital Subscriber Line
نویسنده
چکیده
This paper describes discrete multi-tone (DMT) line coding, which has become the standard asymmetric digital subscriber line (ADSL) modulation technique as selected by the American National Standards Institute (ANSI) T1E1 committee. Presented here is an overview of DMT ADSL including quadrature amplitude modulation (QAM) encoding, rate-adaptation, bitswapping as well as some of the overall advantages to using DMT for ADSL modulation.

Frame Synchronization Exploiting Cauchy Distribution in DMT-Based xDSL Modems
This letter considers frame synchronization in nonsynchronized sampling discrete multi-tone (DMT) based asymmetric digital subscriber line (ADSL)/very high speed DSL (VDSL) systems in the presence of timing error. We propose a frame synchronization method which is based on the observation that the normalized correlation between two sequences separated by the FFT length is Cauchy random variable...
متن کاملCombination of per Tone Equalization and Windowing Indmt -
High speed Digital Subscriber Line (DSL) systems transmit signals that overlap in spectrum with the bands used for radio communications. AM broadcast stations and radio amateur transmitters result into electromagnetic interference impairing the DSL-receiver. For Discrete Multitone (DMT) systems, windowing, in combination with Radio Frequency Interference (RFI) cancellation has been proposed to ...
متن کاملTCP performance analysis and optimization over DMT based ADSL systems
This paper studies the transmission control protocol (TCP) performance over a discrete multi-tone (DMT) based asymmetric digital subscriber loop (ADSL) network. The impact of DMT subchannel bit loading on the TCP throughput performance is studied. The simulation results show that there is a threshold for the signal-to-noise ratio (SNR) gap or bit error rate (BER) above which TCP throughput drop...

An all-digital implementation of multicarrier modulation called discrete multitone (DMT) modulation has been standardised for asymmetric digital subscriber line (ADSL), ADSL2, ADSL2+ and VDSL [1][3]. ADSL modems rely on DMT modulation, which divides a broadband channel into many narrowband subchannels and modulated encoded signals onto the narrowband subchannels [4], [5]. With advanced digital ...
