    • A method for mapping a secondary synchronization channel symbol in an OFDM cellular system and a base station using the same remove unclearness between other cells in a mapping proves by setting at least one of two orthogonal code sequences to an index value to add or multiply an arbitrary number to or by the orthogonal code sequence index allocated to a first secondary synchronization channel symbol and performing mapping. A first orthogonal code sequence(301) and a second orthogonal code sequence(302) allocated to the first secondary synchronization channel symbol are cross-mapped and allocated to a second secondary synchronization channel symbol. At least one of two orthogonal code sequences is set to an index value adding or multiply the arbitrary number to or by the orthogonal code sequence index allocated to the first secondary synchronization channel symbol and then is mapped. The arbitrary number is the natural number.
    • 通过将两个正交码序列中的至少一个设置为索引值来在OFDM细胞系统和基站中使用相同的删除不清楚的映射中的其他小区之间的映射的方法,以添加或乘以任意的 编号分配给或分配给第一次要同步信道符号并执行映射的正交码序列索引。 分配给第一次同步信道符号的第一正交码序列(301)和第二正交码序列(302)被交叉映射并分配给第二次同步信道符号。 两个正交码序列中的至少一个被设置为将任意数加到或乘以分配给第一次同步信道符号的正交码序列索引然后被映射的索引值。 任意数字是自然数。
