In this paper, we propose a construction of periodic complete complementary codes composed of the expanded modulatable orthogonal sequences. Because the number of the expanded modulatable orthogonal sequences of period N2 is infinite, the number of the periodic complete complementary codes of period N2 is also infinite. It is already proved that the proposed sequences are periodic complete complementary codes. In the meantime, Suehiro has proposed a signal design method for approximately synchronized CDMA systems without co-channel interference. In this signal design method, we can assign the proposed periodic complete complementary codes as code words to each user so that the information transmission rate is increased.
