| Abstract(in English) | Orthogonal spreading codes have been applied to multiple access for communication systems. Tree structured orthogonal spreading codes with different code lengths have been developedand applied to the practical wireless communication systems to support multi-rate services. Recently they have been extended to non-binary polyphase codes over the complex field. This paper proposes a construction method of the orthogonalspreading codes with different code lengths over finite fields, and shows their applications to the multi-rate communications. |
