Fischer and Huber : Comparison of Precoding Schemes for Digital Subscriber Lines
نویسنده
چکیده
| Precoding at the transmitter side is a practicable method for transmission over intersymbol interference channels. In contrast to decision{feedback equalization no error propagation occurs and coded modulation can be applied as for the intersymbol interference free channel. In this paper, Tomlinson{Harashima precoding and exible preco-ding are analyzed and compared. The dualities and diie-rences are discussed. The focus of interest is the application of precoding to fast digital transmission over twisted pair lines, such as high{rate or asymmetric digital subscriber lines. It turns out that exibility | which is not necessary in the speciic application, digital subscriber lines | of exi-ble precoding is paid with a performance loss compared to Tomlinson{Harashima precoding.

متن کاملSignal shaping for peak-power and dynamics reduction in transmission schemes employing precoding
Precoding, i.e., nonlinear pre-equalization, at the transmitter side has been proved to be a very efficient strategy for channel equalization in single-carrier digital transmission schemes. It enables the application of coded modulation in a seamless fashion. A drawback of precoding is that the signal at the input of the decision device exhibits a huge dynamic range. Based on dynamics shaping, ...
متن کاملDynamics Limited Precoding, Shaping, and Blind Equalization for Fast Digital Transmission over Twisted Pair Lines
|A new combined precoding/shaping technique for fast digital transmission over twisted pair lines is proposed. Major advantages of this \dynamics shaping" are: Dynamics of the signal at the input of the decision device are reduced by a great amount. Thereby, A/D-conversion, adaptive equalization, and symbol timing are rather facilitated. A trade-o between signal dynamics at the transmitter outp...

متن کاملBlind Equalization Techniques for xDSL using Channel Coding and Precoding
A new concept for digital communication over severe intersymbol interference producing channels, e.g., high–rate digital transmission over twisted pair lines (xDSL techniques) is proposed including channel coding, precoding, equalization, and synchronization. Channel coding improves data reliability or tolerable signal attenuation, e.g., field length, whereas a nonlinear predistortion method, a...
