摘要
最佳高斯整数序列应用于通信系统不仅能抑制干扰，还可获得高的传输速率和频谱利用率.本文基于循环差集给出了构造自由度为2的最佳高斯整数序列的充要条件，比较现有文献，可获得更高能量效率的最佳高斯整数序列.同时，利用上采样和过滤技术扩展了最佳高斯整数序列的长度和自由度.本文方法能得到大量适于高速通信系统的最佳高斯整数序列，扩展了通信地址码的选择范围.
Abstract
Perfect Gaussian integer sequences applied to communication systems can not only restrain disturbance
but also obtain high transmission rates and spectrum utilization. In this paper
the sufficient and necessary condition for constructing the perfect Gaussian integer sequences with 2-degree freedom is given based on the cyclic difference sets. The perfect Gaussian integer sequences with higher energy efficiency can be obtained compared to the existing literatures. The length and degree of freedom of the perfect Gaussian integer sequences are extended by up-sampling and filtering. A large number of perfect Gaussian integer sequences obtained in this paper are suitable for high speed communication applications
which expands the selection range of address codes.
