Bose and Lin introduced a class of systematic codes for detection of binary asymmetric errors. In this note, we describe a generalization to q-ary asymmetric error detecting codes. For these codes, the possible undetectable errors are characterized and the undetectable errors of minimum weight are determined 相似文献

A new procedure is presented for the synthesis of diagonal compensators for N × N linear multivariable systems that are free of fixed modes with respect to constant diagonal output feedbacks. The synthesis procedure employs simple polynomial algebra and it is in the form of an N-step algorithm. The geometric configurations 2N- and 2N-cells in N-space are shown to be especially suitable for visualizing diagonal feedback and aiding the application of the synthesis algorithm. 相似文献

Holographically recorded surface relief gratings in dry, self-developing acrylamide based photopolymer were used to fabricate
two types of switchable liquid crystal (LC) device. One is an electrically switchable LC diffraction grating and the other
is an electrically switchable polarization rotator. The electrically switchable diffraction grating was characterized by measuring
the dependence of the intensity in the first diffracted order on the applied electric field. The polarization rotator was
characterized by studying the influence of the applied electric field on the twist angle and the variation of intensity in
the zero and the first orders of diffraction. 相似文献
