Improved initialization for time domain equalization in ADSL
An improved optimization algorithm for the time domain equalizer (TEQ) is developed for discrete multitone (DMT) based asymmetric digital subscriber line (ADSL). In contrast with existing algorithms, our algorithm explicitly disregards the unused tones in the cost function as well as in the non-triviality constraint. Simulation results are presented for the upstream channel. It is shown that th...

| An improved optimization algorithm for the time domain equalizer (TEQ) is developed in case of Frequency Division Multiplexing-based Asymmetric Digital Subscriber Line (FDM-ADSL). In contrast with existing algorithms, our algorithm explicitly disregards the unused tones in the optimization function as well as in the non-triviality constraint. Some simulation results are presented for the upst...
متن کاملImproved Time-domain Equalizer Initialization Algorithm for Adsl Modems
In this paper, we propose an improved adaptive initialization algorithm for the time domain equalizer in an FDM-based Asymmetric Digital Subscriber Line (ADSL). Using our developed approach, higher convergence rate than that of the commonly used Least-Mean Square algorithm is obtained, whilst attaining bit rates close to the optimum Maximum Shortening SNR and the upper bound Match Filter Bound ...
متن کاملAdvanced Algorithms for Equalization on Adsl Channel
Digital subscriber line modems equalize response of line (channel) to fight with interferences and line dispersion which down the bit-rate of transmission. Main equalization principle is “Channel shortening” which is the base for time domain equalizers (TEQ). Many TEQ algorithms have been already proposed, mainly in theoretical sense. With growth of hardware performance, more complex methods ca...
متن کاملDWMT transceiver equalization using overlap FDE for downlink ADSL
Discrete wavelet multitone (DWMT) modulation is a wavelet transform based technique implemented using perfect reconstruction filter banks. It has been recently proposed for various wireline channels such as digital subscriber loops (DSLs) as a solution to the problems posed by a discrete multitone (DMT) transceiver including interblock interference (IBI) and lower spectral efficiency due to the...
