| Abstract(in English) | This paper investigates the bit error rate performance of synchronous optical code-division multiple access (CDMA) using chip-pair codes. The class of chip-pair codes is a proper subset of the class of generalized modified prime sequence codes (GMPSCs). The chip pair codes are constructed from any extension fields GF($p^m$), where $p$ is a prime number and $m$ is a positive integer. Optical CDMA systems with chip-pair codes remove optical interference (e.g., background light) whose intensity varies by shorter blocks with a length of $p$, while those with GMPSCs remove optical interference whose intensity varies by longer blocks with a length of $p^m$. Present paper investigates the bit error rate performances of optical CDMA with chip-pair codes under the condition that the intensity of the interference light varies continuously. It is shown that the bit error rate performances for chip-pair codes are better than those for the original GMPSCs when there exists a continuously and periodically varying interference light. |
