中文摘要：
为了改善传统扩频序列的性能,提出了构造一种基于Gold和Walsh序列的复合序列的方法。对m、Gold以及Walsh等传统扩频序列的产生和相关特性进行了研究。在此基础上,针对Walsh序列相关性能不够理想的特点,通过将序列循环相乘,利用复合序列的基本思想将Gold序列与Walsh序列相组合,设计出这种新的复合序列,即Gold-Walsh序列。仿真实验结果表明,该复合序列与传统扩频序列相比较,具有较优的相关特性。
英文摘要：
To improve the property of traditional spreading sequence, a new composite sequence method based on gold sequence and Walsh sequence is proposed.The generation and correlation properties of m sequence, Gold sequence and Walsh sequence are analyzed.Due to the non-perfect correlation property of Walsh sequence, multiplied the loop sequences, Gold sequence and Walsh sequence are compounded by using the main idea of the composite sequence.Then a new composite Gold-Walsh sequence is designed.The comparison experiment on the traditional coding sequences and Gold-Walsh sequence is done.Simulation result shows the superior correlation property of the composite spreading sequence.
