Abstract: PURPOSE: A synchronization gaining device with respect to asynchronous wideband DS/CDMA(Direct-Sequence/Code Division Multiple Access) receiving signal is provided to determine if the synchronization is gained by differentially coherent combining the ith output with the (I-1)th output of the match filter for the L number of sectors. CONSTITUTION: A long-code masking correlator(500) correlates the control channel signal and the generated common short-code. A differential combiner(502) differentially combines the results of correlation and then determines the gain of synchronization of the slot. A GIC(Group Identification Code) gain unit(504) correlates the GIC and LC masking sector and combines the results of match filtering of one frame or the more times as the positive number to select a GIC of highest output value. The GIC selected is determined to be the code group of the base station where the terminal belongs to and the frame synchronization is gained at the same time. An LG(Long Code) gaining unit(506) match-filters the W number of LC belonging to the code group gained by the GIC gaining unit and the sectors other than the LC making sector to select the LC of the highest value.

Abstract translation: 目的：提供相对于异步宽带DS / CDMA（直接序列/码分多址）接收信号的同步增益装置，以确定是否通过将第i个输出与第（I-1）个第 输出L个扇区的匹配滤波器。 构成：长码屏蔽相关器（500）将控制信道信号和所生成的公共短码相关联。 差分组合器（502）差分地组合相关的结果，然后确定时隙的同步增益。 GIC（组识别码）增益单元（504）使GIC和LC屏蔽扇区相关，并将一帧或更多次的匹配滤波结果组合为正数，以选择最高输出值的GIC。 所选择的GIC被确定为终端所属的基站的码组，同时获得帧同步。 LG（长码）获取单元（506）对属于由GIC获得单元获得的代码组的LC值和LC制造扇区之外的扇区进行匹配滤波，以选择最高值的LC。
