چکیده

Abstract—The influence of mutual coupling among multiple input multiple output antenna (MIMO) systems is usually not negligible due to limited antenna spacing available in practice. A thorough understanding of such influence, however, is not available in the literature, although it is important to the design of a transmission strategy. In this paper, by formulating the equivalent channel matrix in terms of S-parameters that characterize mutual coupling, we obtain an explicit expression for the channel capacity. The maximization of the channel capacity so obtained leads to the optimal pre-coding strategy for the transmitter. Numerical examples are presented to illustrate the theory.

Microsoft Word - V2-I2-P64-69

Using concave rectangular patches, a new solution to reduce mutual coupling and return loss in two-dimensional array of microstrip antennas is proposed. The effect of width and length concavity on mutual coupling and return loss is studied. Also, the patch parameters as well as the amounts of width and length concavity are optimized using an enhanced genetic algorithm. Simulation results show t...

Microsoft Word - ISMRM2009-001038.DOC

Introduction: This abstract presents a new approach towards a fast, simultaneous B1 and T1 mapping technique. This is especially important due to the mutual dependency of these parameters. The new method is based on the “actual flip angle imaging” (AFI) sequence [1], however, using multiple TR pairs instead of the standard AFI approach of a single TR pair. In the following, this multiple TR met...

Automatic Corpus-Based Thai Word Extraction with the C4.5 Learning Algorithm VIRACH SORNLERTLAMVANICH, TANAPONG POTIPITI AND THATSANEE CHAROENPORN

Word” is difficult to define in the languages that do not exhibit explicit word boundary, such as Thai. Traditional methods on defining words for this kind of languages have to depend on human judgement which bases on unclear criteria or procedures, and have several limitations. This paper proposes an algorithm for word extraction from Thai texts without borrowing a hand from word segmentation....

Evaluation of Stop Word Lists in Chinese Language

In modern information retrieval systems, effective indexing can be achieved by removal of stop words. Till now many stop word lists have been developed for English language. However, no standard stop word list has been constructed for Chinese language yet. With the fast development of information retrieval in Chinese language, exploring the evaluation of Chinese stop word lists becomes critical...

Neural Word Embedding as Implicit Matrix Factorization

We analyze skip-gram with negative-sampling (SGNS), a word embedding method introduced by Mikolov et al., and show that it is implicitly factorizing a word-context matrix, whose cells are the pointwise mutual information (PMI) of the respective word and context pairs, shifted by a global constant. We find that another embedding method, NCE, is implicitly factorizing a similar matrix, where each...
