多載波通訊系統之通道估計方法

一種多載波通訊系統之通道估計方法,其係在正交分頻多工(OFDM)及正交分頻多工存取(OFDMA)使用相位旋轉多項式插補之通道估計。在OFDM及OFDMA系統基於複雜度的考量,經常採取多項式插補演算法來做通道估計,其中以線性插補法為最簡便之插補法。然而多項式插補演算法之效能取決於符碼時間同步的精準度以及通道延滯擴散。本發明藉由一線性相位參數加至多項式插補器上,此一線性參數相當於在時域加入一時間延滯量(稱為延遲偏移),以求得較佳之相位旋轉多項式插補效能。

METHOD FOR OFDM AND OFDMA CHANNEL ESTIMATION
(2009-09-17)
HUNG, Kun-Chien
;
Lin, David W.
This invention discloses a method for OFDM and OFDMA channel estimation via phase-rotated polynomial interpolation and extrapolation (inter/extra-polation). For complexity reason, polynomial inter/extra-polation is an often considered method for channel estimation in orthogonal frequency-division multiplexing (OFDM) and orthogonal frequency-division multiple access (OFDMA) systems, in which the simplest choice is linear inter/extra-polation. But the performance of this method depends on the accuracy of symbol timing estimation as well as the channel delay spread. The invention mitigates the problem by adding a linear phase factor to polynomial inter/extra-polation, which corresponds to adding a delay (also called delay shift) in the time domain.

【課題】高分子太陽電池の製造工程を簡素化し、高分子太陽電池の光電変換効率を高める。【解決手段】有機活性層材料溶液は、有機活性層材料、第１の有機溶媒及びより沸点の高い第２の有機溶媒から構成される。第１の有機溶媒の沸点は５０～２００℃であり、第２の有機溶媒の沸点は１５０～３００℃である。第２の有機溶媒を第１の有機溶媒に加え、有機活性層材料を溶解する。第２の有機溶媒の沸点は高い（揮発速度が遅い）ので有機活性層溶液の揮発速度を低下させるため、溶液アニールにおける環境を有機活性層溶液を高飽和蒸気圧環境または密閉環境に維持する必要がなく、高分子太陽電池の製造工程を簡素化し、高分子太陽電池の光電変換効率を高めることができる。【選択図】図２

A two-terminal quantum-dot infrared photodetector with stacked five-period InAs/GaAs and InGaAs-capped InAs/GaAs quantum-dot (QD) structures is investigated. The device has exhibited distinct responses at mid-wavelength and long-wavelength infrared regions under positive and negative biases, respectively. The results suggest that the QD confinement states near the anode side are completely filled, such that selective responses at different wavelength ranges would be observed for the stacked structure under different voltage polarities. Also observed are the similar absorption ratios of the device under different incident light polarizations at the two response regions. (C) 2009 American Institute of Physics.

The optical properties of an annular periodic multilayer structure containing two kinds of single-negative materials are theoretically investigated based on the transfer matrix method of the cylindrical waves. At the azimuthal mode number m >= 1 and near the magnetic plasma frequency and the electronic plasma frequency for the TE wave and TM wave, respectively. we find that there is an additional high-reflectance band and some reflection dips exist when the plasma frequency is located in the photonic band gap. These two special features arising from the higher order azimuthal mode of the cylindrical waves are not seen in the planar one-dimensional Bragg reflector consisting of the single-negative materials. Such filtering responses provide a feasible way of designing a narrowband resonator without physically introducing any defect layer in the structure. (C) 2009 Elsevier B.V. All rights reserved.

Secondary electron potential contrast (SEPC) technology with an in situ dynamic trigger was studied to inspect P(+)/N-well junction leakage arising from P-well misalignment in a static random access memory cell. Combining SEPC with scanning electron microscopy observations allows direct identification of the junction shift. Furthermore, an in situ negative bias applied to the P-well can create a wider depletion region and eliminate the leakage path in P(+)/N-well contacts, allowing the P(+)/N well to operate normally. This proposed in situ dynamic trigger method is a promising and effective approach to investigating device physics under a dynamic scope. (C) 2009 American Institute of Physics.
