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.

Key words: perfect Gaussian integer sequences, cyclic difference sets, degree of freedom, energy efficiency
