摘要： The present invention relates to a demodulation method for enhancing decoding performance of information bits in a constant-amplitude multi-code biorthogonal modulation communication system, which performs encoding to cause the level of a transmission symbol to be constant. In the demodulation method of the present invention, a demodulator demodulates the received signal, the demodulator having four blocks. C (c≦2k, k is the number of information bits) bit streams with higher correlation values in descending order are selected and combined among demodulated bit streams to establish c4 bit stream candidates. A parity check is performed with respect to the c4 bit stream candidates, a candidate group having a maximal sum of correlation values is selected among candidate groups in which any error is not generated at the parity check. A bit stream corresponding to the selected candidate group is determined to be an output of a receiver. If a hypothesis in which any error is not generated does not exist, a bit stream determined using a maximum correlation value with respect to each of the blocks is output. According to the present invention, there is an advantage in that an error in reception bits can be detected or corrected, thus improving reception performance.
摘要翻译： 本发明涉及一种在恒定幅度多码双正交调制通信系统中增强信息比特的解码性能的解调方法，该系统执行编码以使得传输符号的电平恒定。 在本发明的解调方法中，解调器对接收信号进行解调，解调器具有四个块。 C（c <= 2K k，k是信息比特数），选择具有较高相关值的比特流，并且在解调比特流之间进行组合以建立c 4 >位流候选。 对于第4个比特流候选进行奇偶校验，在奇偶校验检查中不产生任何错误的候选组中选择具有最大相关值之和的候选组。 对应于所选择的候选组的比特流被确定为接收机的输出。 如果不存在产生任何错误的假设，则输出使用相对于每个块的最大相关值确定的比特流。 根据本发明，存在可以检测或校正接收位中的错误的优点，从而提高接收性能。

摘要： A refrigerator including an improved lower cover. The refrigerator comprises a main body having a storage compartment defined therein, and a lower cover mounted to the lower end of the front part of the main body such that the front part of the lower cover and the front part of the main body together form the same plane, wherein the lower cover is provided with an engaging member bent from the upper end of the lower cover toward the rear of the main body while being extended a prescribed length, the engaging member being successively formed in the lateral direction thereof, and wherein the main body is provided at the bottom part thereof with an engaging groove corresponding to the engaging member of the lower cover, the engaging member of the lower cover being engaged with the engaging groove of the main body. The lower cover is not protruded from the front part of the main body, and fixed parts of the lower cover are not exposed to the outside, whereby an aesthetic appearance of the refrigerator is provided, and formation of a gap between the lower cover and the lower end of main body is prevented.
