计算机搜寻平衡Gold序列方法研究

分析了平衡、不平衡伪随机Gold序列对通信系统通信质量的影响,通过对Gold序列产生方法的研究,提出了平衡Gold序列的2种计算机搜寻方法,并通过这2种搜寻方法的比较,分析了其不同特点及其适用情况.该研究来源于“高动态、高码率、多通道数字解扩接收机”项目对伪随机序列的需求,用文中方法搜寻了长度分别为15位、31位、63位、127位、255位、511位的平衡Gold序列各6组,并在项目中成功应用.

Research the Ways of Searching Balanceable Gold Sequences

The paper analyzes how the imbalance of Gold sequence impact the quality of communication system. After studying the method to produce Gold sequence the paper gives two ways of getting balanceable Gold sequences in software. By comparing the two ways the paper also analyzes their character under different case. To meet the need of pseudorandom code in the project "digital dispread spectrum receiver of high dynamic and high code rate and multicenter" , the author achieves balanceable six group of Gold sequences respectively which are 15bit,31bit,63bit,127bit,511bit and used successfully in this project.
