| Abstract: | In this paper, a new construction of inter-group complementary (IGC) codes is proposed based on Z-complementary codes and perfect periodic cross-correlation (PPCC) codes. The correlation properties of the new generated IGC codes are as follows: (1) the autocorrelation sidelobe values of the codes are zeros in the zero correlation zone (ZCZ), (2) the cross-correlation values between different codes in the same group are zeros in the ZCZ, (3) the cross-correlation values between codes of different groups are zeros during the whole period. Comparing to the existed IGC codes, the ZCZ length of the generated IGC codes can be predefined flexibly; the number of groups and the number of codes in each group have more freedom according to the advantages of Z-complementary codes and PPCC codes. |
