在这篇文章中，我们提出了一套用于多载波CDMA系统的循环移位正交互补码。传统的OC代码不适合系统，因为它们只能支持有限数量的用户。将所提出的循环oc码应用于无码间干扰（ISI）的多载波系统，可以将用户数量扩展到码长大小。通过仿真验证了所提方案的有效性
In this letter, we present a set of cyclic shifted orthogonal complementary (cyclic-OC) codes for multicarrier CDMA systems. The conventional OC codes are not adequate for the system because they are able to support only the limited number of users. By applying the proposed cyclic-OC codes for the inter-symbol interference (ISI)-free multicarrier systems, the number of users can be extended to the size of code length. We validate the effectiveness of the proposed scheme through simulations
