| Abstract(in English) | Suehiro expanded the concept of the complete complementary codes and has proposed periodic complete complementary codes composed of modulatable orthogonal sequences. On the other hand, Torii and Suehiro have proposed expansion of modulation for modulatable orthogonal sequences. 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 N^2 is infinite, the number of the periodic complete complementary codes of period N^2 is also infinite. Suehiro has proposed a signal design method for approximatery 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. |
