We study error statistics of lattice quantization with and without vector dithering. As in the scalar case, we distinguish between subtractive and nonsubtractive dithering. We derive general expressions for appropriate error statistics in both cases. In subtractive dithering , we can achieve statistical independence of the error vector from the input vector by appropriate choice of the dither v...

In power-over-fiber systems, simultaneous data signals and power transmission using a single optical fiber is an attractive step towards simplifying the systems. However, when simultaneously transmitting feed light in core, quality of signal degrades owing to crosstalk based on characteristics source. this study, we investigate evaluate between high-power system. To observe effect more clearly,...

The error distribution is generally unknown in deconvolution problems with real applications. A separate independent experiment is thus often conducted to collect the additional noise data in those studies. In this paper, we study the nonparametric deconvolution estimation from a contaminated sample coupled with an additional noise sample. A ridge-based kernel deconvolution estimator is propose...

Error correcting output codes (ECOC) have been proposed to enhance generalization ability of classifiers. If, instead of discrete error functions, continuous error functions are used, unclassifiable regions of multiclass support vector machines are resolved. In this paper, we discuss minimum operations as well as average operations for error functions of support vector machines and show the equ...

An all-optical radio-over-fiber (RoF) link with double spectral-efficient transmission and compensation of chromatic dispersion-induced power fading is proposed experimentally demonstrated. At the central office, a commercial dual-polarization quadrature phase-shift keying modulator utilized to produce polarization-multiplexed signal composed two modulated microwave vector signals an unmodulate...
