あらまし サイクリックプレフィックス (CP)を用いたブロック伝送では,CPの付加及び除去を含めた通信路 が巡回行列で記述されるが,ガード時間 (GI) を超える遅延波が存在する場合などには巡回行列の一部の成分が 欠落した行列(不完全巡回行列)による信号ひずみが観測される.本論文では,CP を用いたブロック伝送方式, 特にシングルキャリヤのブロック伝送 (SC-CP) 方式を対象に,不完全巡回行列による信号ひずみを少ない要求 演算量で補償する手法を提案する.提案方式では,新たに導出したMMSE (Minimum Mean-Square-Error)基 準離散周波数領域等化器重みとその等化器出力信号の信頼度の違いを利用した擬似逆行列による等化器によって, 不完全巡回行列による信号ひずみを巡回行列による信号ひずみに変換することで,従来からの離散周波数領域等 化器を利用可能にする.計算機シ...

The effect of magnetic field on the growth of bacteria was studied with the series piezoelectric quartz crystal (SPQC) sensing technique. The growth situations of Escherichia coli (E. coli) in the absence and presence of different intensities of static magnetic fields were examined and analyzed. The results showed that the growth of E. coli was inhibited due to the presence of magnetic fields. ...

Guanosine triphosphate binding proteincoupled receptors (GPCRs) represent one of the largest and most important classes of pharmaceutical drug targets. Approximately 48% of all GPCRs couple through adenylate cyclase making the need for a robust cAMP detection method critical. We have developed a secondgeneration LANCE® time-resolved fluorescence resonance energy transfer (TR-FRET) immunoassay d...

natural vibration analysis of plates represents an important issue in engineering applications. in this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. the design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. the dynamics of the plate i...

Infectious bronchitis virus (IBV) is distributed worldwide and causes significant losses in the poultry industry. In recent decades, lineages GI-19 GI-7 have become most prevalent IBV strains China. However, molecular evolution phylodynamics of lineage remain largely unknown. this study, we identified 19 from clinical samples January 2021 to June 2022 China, including 12 GI-19, 3 GI-7, 1 strain...
