Short-Sampled Blind Source Separation of Rotating Machinery Signals Based on Spectrum Correction by Xiangdong Huang, Xukang Jin, Haipeng Fu

“…Through the incorporation of FFT, spectrum correction, a screen procedure (consisting of frequency merging, candidate pattern selection, and single-source-component recognition), modified k-means based source number estimation, and mixing matrix estimation, the proposed BSS algorithm can accurately achieve harmonics sensing on field rotating machinery faults in case of short-sampled observations. Both numerical simulation and practical experiment verify the proposed BSS algorithm’s superiority in the recovery quality, stability to insufficient samples, and efficiency over the existing ICA-based methods. …”

Trends and enabling technologies on high-speed metro and short-reach optical transmission systems by Lei ZHANG, Yixiao ZHU, Fan ZHANG, Zhangyuan CHEN

“…The optical fiber communication network is the important infrastructure for the modern information society.Thanks to the reduction of fiber loss,the improvement of transceiver devices by electro-optical-electrical conversion,the development of modulation technology and the introduction of digital signal processing,the capacity of optical fiber transmission has been greatly improved.In recent years,due to the large capacity demand of data-centers and the next-generation wireless communication,metro and short-range transmission scenarios below 100 km have attracted lots of attention based on direct detection.The historical evolution of optical fiber communication systems was firstly reviewed,then the limiting factors in the direct detection system were analyzed.Furthermore,the principle and system configuration of one-dimensional to four-dimensional self-coherent technology were introduced,and finally,the low-cost evolution trend of the optical coherent transmission system was prospected.…”
