    • Provided is a frame synchronization apparatus capable of reducing the amount of total computation and computation delays when a receiver of a satellite communication system calculates correlation between an input signal for frame synchronization and a signal sequence of the receiver, since the receiver uses no multiplier. The frame synchronization apparatus includes a correlator to obtain a correlation value of a unique word of a receiver with respect to a symbol data stream of a frame received from a transmitter of the satellite communication system, a comparator to compare the correlation value to a predetermined threshold value, and a determiner to determine whether the frame has been synchronized, based on the result of the comparison by the comparator.
    • 提供了一种帧同步装置,当卫星通信系统的接收机计算用于帧同步的输入信号与接收机的信号序列之间的相关性时,能够减少总计算量和计算延迟量,因为接收机不使用乘法器。 帧同步装置包括相关器,用于相对于从卫星通信系统的发射机接收到的帧的符号数据流获得接收机的唯一字的相关值;将相关值与预定阈值进行比较的比较器 值,以及基于比较器的比较结果来确定帧是否已被同步的确定器。
