    • The present invention provides an apparatus and method for code group identification and frame synchronization for cell searching used in wide-band DS-CDMA cellular systems. This method characterizes each secondary synchronization code sequence (SSCS) with a corresponding theoretical frequency sequence, which represents the occurrence times of CS1 to CS16 in a corresponding SSCS. Thus, 64 secondary synchronization code sequences corresponding to 64 code groups defined in DS-CDMA systems also corresponds to 64 theoretical frequency sequences. By characterizing the SSCS transmitted by a base station, a real frequency sequence can be generated. Comparing the real frequency sequence with the 64 theoretical frequency sequences, one can determine one or two candidate code groups, which may be employed by the base station. Finally, one can compare the SSCS transmitted by the base station with all the possible SSCSs corresponding to the candidate code groups to determine a specific code group and a frame boundary for the base station.
    • 本发明提供了一种用于在宽带DS-CDMA蜂窝系统中使用的小区搜索的码组识别和帧同步的装置和方法。 该方法用相应的理论频率序列来表征每个次同步码序列(SSCS),其表示在对应的SSCS中的CS1到CS16的发生时间。 因此,对应于在DS-CDMA系统中定义的64个码组的64个辅同步码序列也对应于64个理论频率序列。 通过表征由基站发送的SSCS,可以产生实际频率序列。 将实际频率序列与64个理论频率序列进行比较,可以确定基站可以使用的一个或两个候选码组。 最后,可以将由基站发送的SSCS与对应于候选码组的所有可能的SSCS进行比较,以确定基站的特定码组和帧边界。

The first source line commonly controls two sources of the first and second pixel transistors. The second source line commonly controls two sources of the third and fourth pixel transistors. A positive voltage and a negative voltage are alternatively in time sequence applied to the first and second source lines, respectively. An activate voltage is alternatively in time sequence applied to the first and second source lines, respectively.
