摘要： A cell search method of a wireless communication system is provided to improve the performance of detecting a synchronous channel or control channel, and increase the amount of control information which is loaded on the control channel or the capacity of a terminal. The first S-SCH and second S-SCH exchange the locations of the first SSC and second SSC by combining the first SSC and the second SSC. The SSCs of each S-SCH performs the scrambling by using different scrambling codes to obtain the interference averaging effect. Consequently, the ambiguity due to the SSC detection is reduced.

摘要： A special coding scheme is disclosed for more effectively acquiring a long code and frame timing during a cell search in a CDMA communications system. A code set of length M Q-ary code words including symbols from a set of Q short codes is defined with certain properties. The primary property to be satisfied is that no cyclic shift of a code word yields a valid code word. The other properties to be satisfied are that there is a one-to-one mapping between a long code message and a valid code word, and a decoder should be able to find both the random shift (thereby implicitly finding the frame timing) and the transmitted code word (i.e., its associated long code indication message) in the presence of interference and noise, with some degree of accuracy and reasonable complexity.
摘要翻译：公开了一种特殊的编码方案，用于在CDMA通信系统中的小区搜索期间更有效地获取长码和帧定时。包含来自一组Q个短码的码元的长度为M个Q-ary码字的码组被定义为具有某些特性。要满足的主要特性是码字的循环移位不会产生有效的码字。要满足的其他属性是在长码消息和有效码字之间存在一对一映射，并且解码器应该能够找到随机移位（从而隐式地找到帧定时）和在存在干扰和噪声的情况下发送码字（即，其关联的长码指示消息），具有一定程度的准确性和合理的复杂度。
