摘　　要：16-QAM周期/非周期互补码集应用于多载波通信系统可以获得高的抗干扰性能和传输速率,但其构造结果还不丰富。本文提出了3种交织映射方法,借助四元周期/非周期互补码集构造了五类16-QAM周期/非周期互补码集,扩大了16-QAM周期/非周期互补码集的存在范围。选择不同的交织映射方法,得到序列数量是基础码序列的1倍、2倍或4倍的16-QAM互补码。多载波系统通信中互补码的序列数量对应着载波数,因此构造结果可提供更丰富的载波数量选择,有利于提升通信系统的传输速率。16-QAM periodic/aperiodic complementary code sets can be applied to multicarrier communication systems to obtain excellent anti-interference performance and high transmission rate,but the constructed results are not abundant at present.Three kinds of interleaving and mapping methods are proposed and consequently five classes of 16-QAM periodic/aperiodic complementarity are constructed with the aid of quaternary periodic / aperiodic complementary code sets,which extends the range of 16-QAM periodic/aperiodic complementary code set.Different interleaving and mapping methods can be chosen,and the complementary codes can be obtained in which the number of sequences is one,two times or four times as much as that of basic codes.In multicarrier communication systems,the number of a complementary code denotes the number of carriers,so the resultant code sets can provide more sufficient choices for the number of carriers and are beneficial to improve the rate of communication transmission.
