    摘要: A method for channel coding by a transmitter in a communication system is provided. The method includes determining a degree of coded bits of a Luby-Transform (LT) code based on a coding rate of a pre-code and the number of coded bits of the LT code, selecting at least one associated bit used for coding of the coded bits of the LT code from among information bits of the LT code, depending on the determined degree, and generating the coded bits of the LT code by applying a coding function to the selected associated bits.

    摘要: The present invention provides a semiconductor based photovoltaic device and a manufacturing method thereof. The semiconductor based photovoltaic device is able to absorb light with a wide band wavelength, and has high photoelectric conversion efficiency since it has high electron-hole pair separation efficiency. More specifically, the method for manufacturing the photovoltaic device comprises the steps of: a) forming a thin semiconductor quantum dot film on a p or n-type semiconductor substrate, wherein the thin semiconductor quantum dot film includes semiconductor quantum dots inside a medium at which the same type of impurities as the semiconductor substrate are doped; b) forming a pore array through partial etching, wherein the pore array penetrates the thin semiconductor quantum dot film; c) depositing a semiconductor in which complementary impurities to the semiconductor substrate are doped on the thin semiconductor quantum dot film at which the pore array is formed; and d) forming sequentially a transparent conductive film and an upper electrode on the semiconductor in which the complementary impurities are doped and forming a lower electrode at a lower portion of the semiconductor substrate.
