    • A method of independently generating row parity information and column parity information in an encoding process using a low density parity check (LDPC) matrix includes generating code word vectors by generating column parity information using a parity check matrix and message information; selecting code word bits for generating row parity information among code word bits in the generated code word vectors; and generating the row parity information using the selected code word bits, where the selecting of the code word bits comprises: excluding code word bits related to the generation of other row parity information. Accordingly, independent parity information can be generated by generating row parity information on the basis of code word bits without related to generation of column parity information.
    • 在使用低密度奇偶校验(LDPC)矩阵的编码处理中独立地生成行奇偶校验信息和列奇偶校验信息的方法包括通过使用奇偶校验矩阵和消息信息生成列奇偶校验信息来生成码字向量; 选择用于在所生成的码字矢量中的码字位之间产生行奇偶校验信息的码字位; 以及使用所选择的码字比特生成行奇偶校验信息,其中码字比特的选择包括:排除与生成其他行奇偶校验信息相关的码字比特。 因此,可以通过基于码字比特生成行奇偶校验信息来生成独立奇偶校验信息,而与生成列奇偶校验信息无关。

    • An electrodeless lighting system includes: a resonator which is installed at an exit of a wave guide for guiding microwave generated from a magnetron and making light pass and microwave resonate therein; a bulb positioned in the resonator and having a luminous portion filled with a luminous material emitting light by the microwave energy and a shaft portion integrally extended from the luminous portion; a resonance control member disposed inside the resonator and having a height controlled according to a position of the luminous portion of the bulb and the entire length of the resonator so as to make optimum resonance of the microwave; and a reflector positioned around the resonator for reflecting light emitted from the bulb. Accordingly, the electrodeless lighting system can facilitate light distribution for achieving lateral lighting and a wider range of lighting and simultaneously improve lighting efficiency.
    • 无电极照明系统包括:谐振器,其安装在波导的出口处,用于引导从磁控管产生的微波并使光通过和微波谐振; 位于谐振器中的灯泡,具有填充有通过微波能量发光的发光体的发光部分和从发光部分整体延伸的轴部; 谐振控制构件,其设置在所述谐振器内部,并且具有根据所述灯泡的发光部分的位置和所述谐振器的整个长度的高度控制的高度,以使所述微波达到最佳谐振; 以及围绕所述谐振器定位的用于反射从所述灯泡发射的光的反射器。 因此,无电极照明系统可以促进用于实现侧向照明和更宽范围的照明的光分布并同时提高照明效率。
