    • Provided are repetition apparatus and method for repeatedly transmitting and receiving a data packet using different puncturing patterns to overcome signal attenuation and fading in a high speed mobile environment by repeatedly transmitting the duplicated information bit sequences with parity bits having a different puncturing pattern after channel-encoding the duplicated information bit. The repetition apparatus for repeatedly transmitting a data packet, includes a dual data generator for generating duplicated information bit sequences identical to each of information bit sequences to transmit, a channel encoder for dividing each of the duplicated information bit sequences into a plurality of information bits, and generating coded data packets alternately having a plurality of parity bits according to different puncturing patterns for each of the divided information bits, and a transmitter for transmitting the generated coded data packets sequentially.
    • 提供了一种重复装置和方法,用于使用不同的打孔模式重复地发送和接收数据包,以通过在频道编码之后重复地发送具有不同打孔图案的奇偶校验位的复制信息比特序列来克服高速移动环境中的信号衰减和衰落 重复的信息位。 用于重复发送数据分组的重复装置包括:双数据产生器,用于产生与要发送的每个信息比特序列相同的重复信息比特序列,用于将每个复制信息比特序列分成多个信息比特的信道编码器, 以及根据用于每个分割的信息比特的不同的删截图案,交替地生成具有多个奇偶校验位的编码数据分组,以及发送器,用于顺序地发送所生成的编码数据分组。

    • Provided are a satellite VSAT apparatus and a control method thereof. The satellite VSAT apparatus according to an exemplary embodiment of the present invention can switch a modulation type of a signal to be transmitted from an indoor unit (IDU) to the outdoor unit to a linear or non-linear type in a case in which outputting of a transmitted signal is not controlled to an outdoor unit due to limitations, that is, there is no function such as an automatic signal level control in a block up-converter (BUC), a case in which transmission output limitation is large due to a lot of interference requirements for an adjacent channel, a case in which the number of adjacent channels (carriers) is large, or a case in which adjacent channel interference is large due to a frequency in a satellite multi-beam environment and polarization reuse, in a satellite VSAT apparatus system which aims at a low-priced user terminal.
    • 提供了一种卫星VSAT装置及其控制方法。 在根据本发明的示例性实施例的卫星VSAT装置可以将输出从室内单元(IDU)到室外单元的信号的调制类型切换到线性或非线性类型, 发送信号由于限制而不被控制到室外机,也就是说,在块升压转换器(BUC)中不存在诸如自动信号电平控制的功能,由于发送信号的发送输出限制大 相邻信道的大量干扰要求,相邻信道(载波)数量大的情况,或由于卫星多波束环境中的频率和极化重用而导致相邻信道干扰较大的情况,在 卫星VSAT装置系统,其目的在于低价格的用户终端。
