WCDMA中Gold序列的研究
Research on the Gold Sequence in WCDMA
扩展频谱通信中的扩频是通过扩频序列实现的，而第三代移动通信中的三大标准(WCDMA、cdma2000和TD-SCDMA)所给出使用的扩频码依旧以正交码序列和伪随机序列为主。因此对伪随机序列和正交码的研究仍然十分重要。本文在介绍移位寄存器序列的基础上，以MATLAB为实验平台，对m序列、Gold序列的产生及其主要特性进行了仿真研究并加以分析比较，包括自相关特性、互相关特性和平衡性的验证。重点对平衡Gold序列进行研究，实现了计算机对平衡Gold序列的搜索，并给出了平衡Gold序列的搜索结果及其数目。
The spread spectrum in Spread spectrum communication is achieved through the spreading sequence, while the standard in the three (WCDMA, cdma2000 and TD-SCDMA) of the third generation mobile communications is still given to the use of the orthogonal code sequences and the pseudo-random sequence-based spreading code sequence. Therefore, the research on the pseudo-random sequence and orthogonal code remains important. On the basis of the introduction to the shift register sequence, in this paper, the m sequence, Gold sequences and their main characteristics were analyzed and compared through MATLAB simulation, including autocorrelation, cross correlation characteristics and balance in nature verification. Focus on the balance-Gold sequences, this paper realized the computer search on the balance-Gold sequences, the search results and its number were given.
