A 10 Gb/s equalizer consisting of analog equalizer and two-tap halfrate decision feedback equalizer (DFE) in a 0.18μm CMOS has been designer. By employing capacitive degeneration and inductive peaking techniques, the analog equalizer achieves large boosting. The pipelined half-rate architecture is used to improve the transmitted data rate in DFE with a small increase in area. Measurement result...

We participated in the English-Chinese cross-language information retrieval (CLIR) E-C tasks in NTCIR6. Considering the special feature of crossing two different languages in CLIR, our main concerns in our experiment are 1) to evaluate the appropriateness of MT as a means of query translation in CLIR, 2) to evaluate the effect of feedback in retrieval model to the performance of CLIR which has ...

Abstract Orthogonal frequency division multiplexing (OFDM) has been attracting much attention for very high-speed data transmission over a frequency-selective fading channel. To improve the performance in a fading channel, some form of antenna diversity technique is necessary. Recently, Alamouti’s space-time coded transmit diversity (STTD) has been gaining a lot of attention for downlink (base-...

In this paper, we propose a novel holistic methodology for keyword search in historical typewritten documents combining synthetic data and user's feedback. The holistic approach treats the word as a single entity and entails the recognition of the whole word rather than of individual characters. Our aim is to search for keywords typed by the user in a large collection of digitized typewritten h...

Relevance Feedback (RF) is a technique allowing to enrich an initial query according to the user feedback in order to get results closer to the user’s information need. This paper presents a new RF method for keyword queries (content queries). It is based on the re-weighting of the original query terms plus the addition of new query terms from the content of elements jugded as relevant or non-r...
