[[abstract]]An adaptive interpolated FIR (IFIR) echo canceller was recently proposed for xDSL applications. This canceller consists of an FIR filter, an IFIR filter, and a tap-weight overlapping and nulling scheme.

Prosodic Modeling Research for Mixed Language
[[abstract]]決策回授等化器(DFE) 是一項被廣泛運用於通訊系中消除符際干擾(ISI)的技術。在有線通訊中,通道響應通常是非常的長,以致DFE的計算複雜度顯得相當的高。當DFE的回授部份實作於傳送器端時,系統將以預先編碼方式運作,此時由於回授訊號的值為連續數值而非離數值,高計算複雜度的問題顯得特別明顯。在本研究計畫中,我們將提出一個內插式決策回授等化器(IDFE)來解決此一問題。所提IDFE,是由一個前向有限脈衝響應(FIR)濾波器和一個回授內插有限脈衝響應濾波(IFIR)所組成 ...

Transmission Capacity of Local Copper Cables
The local cable network (cable plant) is a part of public switched telephone network (PSTN) which connects local telephone exchanges with customer’s premises equipment (CPE). It is built up of multipair twisted cables.

Data Errors in ADSL and SHDSL Systems Due to Impulse Noise
This paper considers the performance of Digital Subscriber Lines (DSL) in the presence of impulse noise in terms of data errors. Impulse noise is one of the biggest impairments for xDSL systems. An analysis of error statistics of transmitted data for two popular versions of xDSL - ADSL and SHDSL - is reported here.

Design of Filters for SHDSL Over POTS
One of the substandard variants of speech signal transmission (POTS - Plain Old Telephone Service) is coexistence with the single-pair high-speed digital subscriber line (SHDSL). It refers to a principle similar to speech signal transmission with the asymmetric digital subscriber line (ADSL over POTS).
