چکیده
Basically, conventional single-carrier system has an advantage in limited power communication systems. However, the performance of conventional single-carrier system is seriously degraded by ISI (inter-symbol interference). In order to overcome the ISI, communication systems are commonly used an equalizer. Turbo equalization technique was proposed to maximize system performance over ISI channel. Turbo equalizer can achieve impressive performance gains over ISI channel. Turbo equalizer performs iterative feedback from decoder to equalizer in receiver. Because of iterative feedback, turbo equalizer gets better system performance according to the iteration number. In this paper, we propose a novel turbo equalizer for compensating ISI, which is called as blind pseudo turbo equalizer. Blind means that the equalizer is used without any kinds of training sequence. And Pseudo turbo equalizer means modified structure of turbo equalizer. Pseudo turbo equalizer is included with feed-forward filter and feedback filter. Therefore, we evaluate the BER performance of blind pseudo turbo equalizer. Keywordssingle-carrier system; ISI; blind pseudo turbo equalizer; iterative feedback.

Bilingual Lexicon Extraction via Pivot Language and Word Alignment Tool
This paper presents a simple and effective method for automatic bilingual lexicon extraction from less-known language pairs. To do this, we bring in a bridge language named the pivot language and adopt information retrieval techniques combined with natural language processing techniques. Moreover, we use a freely available word aligner: Anymalign (Lardilleux et al., 2011) for constructing conte...

متن کاملA New Test Methodology for Word-Oriented Memories
With growing of memory capacity, to detect memory faults is more and more difficult, and its cost increases rapidly. Since these faults seriously decrease the yield rate of memories, it is necessary to find an effective test algorithm for memory to improve the chip yield rate. In these days, as word-oriented memories are broadly used, testing for word-oriented memory becomes more important. In ...
