Compensation for pixel misregistration in volume holographic data storage.
We describe what we believe to be a novel postprocessing algorithm for compensating for misregistrations between a detector array and the coherent image of a pixelated two-dimensional data page. A lookup table of baseline local offsets is combined with the dynamically measured global offset of the received data page, producing an estimate of the total lateral shift of each small block of pixels...
متن کاملPixel–matched phase–conjugate readout for holographic data storage
We demonstrate one-to-one pixel–matching of phase–conjugate digital volume holographic data storage, with data pages as large as a megapel (1024 × 1024 pixels). A self–pumped phase–conjugate mirror in BaTiO3 is used to provide a phase–conjugate reference beam, which reconstructs the data–bearing object beam from a LiNbO3:Fe crystal using the 90◦ geometry. The systems tradeoffs of phase–conjugat...
متن کاملModulation coding for pixel-matched holographic data storage.
We describe a digital holographic storage system for the study of noise sources and the evaluation of modulation and error-correction codes. A precision zoom lens and Fourier transform optics provide pixel-to-pixel matching between any input spatial light modulator and output CCD array over magnifications from 0.8 to 3. Holograms are angle multiplexed in LiNbO(3):Fe by use of the 90 degrees geo...
متن کاملPixel-matched holographic data storage with megabit pages.
Digital data-page holograms consisting of 1024 x 1024 arrays of binary pixels have been stored and subsequently retrieved with an optical exposure consistent with a data rate 1 Gbit /s. Each input pixel was precisely registered with a single detector pixel, and a raw bit-error rate as low as 2.4 x 10(-6) was demonstrated with global-threshold detection. To our knowledge, this is the first demon...
متن کاملIterative Frequency-domain Interference Cancellation of Inter-code Interference and Inter-antenna Interference
あらまし 限られた帯域幅で高速パケット伝送を実現するには,マルチ送受信アンテナ(MIMO)多重とハイブリッド自 動再送要求(HARQ)の併用が有効である.筆者らは最近,マルチコード DS-CDMA MIMO 多重伝送を対象として,繰り返 し周波数領域干渉キャンセル(FDIC)を提案した.2 次元最小平均 2 乗誤差規範に基づく周波数領域等化(2D MMSE-FDE) でコード間干渉(ICI)と他アンテナ干渉(IAI)を低減した上で,FDIC によって残留 IAI を抑圧する.この繰り返し処理によ って信号分離精度を向上させている.しかし,FDIC では残留 IAI のみを抑圧する構成となっており,残留 ICI について はそのままである.そのため,残留 ICI が信号分離精度向上に制限を与えてしまう.そこで本論文では,残留 ICI 及び残 留 IAI を同時に低減する繰り返し FDI...
