摘要： The present invention discloses a transmission device of a low-noise optical signal having a low-noise multi-wavelength light source, a transmission device of broadcast signals using a low-noise multi-wavelength light source, and an optical access network having the same.The present invention uses a low-noise multi-wavelength light source (LMLS) which has sufficiently low noises at respective wavelengths, while being lasing at a multi-wavelength. Noises at respective wavelengths are not increased, even though an output light of such an LMLS passes through a wavelength division multiplexer/demultiplexer (a tunable optical filter or an arrayed waveguide grating (AWG), etc.). When using an LMLS, it is possible to embody an optical access network capable of transmitting optical signals at a high-speed and simultaneously transmitting a multicast signal. Further, when embodying an optical amplifier by using a gain medium for an LMLS, it is possible to obtain gain at a broad band without cross-coupling.

摘要： An apparatus and a method for reallocating segments in a broadband wireless communication system are provided. An average density for all cells in system and an average minimal inter-cell distance R are computed. A circle is determined having a radius kR and a center at a corresponding cell by increasing a constant k until a density of the circle becomes less than or equal to the average density. A cluster is generated for each cell, which is composed of cells included in the determined circle. Accordingly, segment allocation capability can be improved while minimizing a width of segment reallocation.
