  • This paper proposes a new short-term load forecasting method for special day, such as Public holidays, consecutive holidays, and days before and after holidays. when the load curves are quite different from those of normal weekdays. In this paper, two Artificial Neural Network(ANN) systems are applied to short-term load forecasting for spacial days in anomalous load conditions.

  • As we have understood the commonly launched T-DMB service from December 2005, we kindly recommend to apply LCX cable installing solution which can be covering underground subway and tunnel T-DMB signal shadow area with most efficient network implementation method. Subway passengers would be enjoyable continuous T-DMB services through LCX cable installing solution.

  • DVB-C2 is the next generation digital broadcasting standard which will replace the analog cable broadcasting. LDPC and BCH significantly increase performance of forward error correction and allows for the application of higher constellation. Additionally, DVB-C2 is based on OFDM instead of single-carrier modulation, which gives additional flexibility and robustness in typical cable channels. This paper will give an introduction to the DVB-C2 system and spectral efficiency of DVB-C2 compare with DVB-C. Finally, The the simulation which is using BICM and OFDM structure show the performance of the DVB-C2.
