Perfect Gaussian integer sequences (PGIS) applied to spread spectrum communication systems can not only restrain disturbance
but also obtain high transmission efficiency and spectrum efficiency.Therefore
this paper presents a class of PGIS with odd length and nonzero level (i.e.degree) for 2 and 3 based on cyclotomic classes.Simultaneously
using coefficient sequence and interleaving method
the odd length PGIS is extended to even length PGIS.Under certain conditions
based on the construction method of cyclotomic classes
a large number of high energy efficiency PGIS can be obtained
and the maximum energy efficiency is close to 1
which is of great practical significance to the engineering application.The result of this paper provides more address selection space for broadband spread spectrum communication systems.
