A new family of one-dimensional spreading codes for optical CDMA

摘要

In this paper, a new family of one-dimensional (1-D) spreading codes is proposed and constructed by utilizing a one-to-one correspondence algorithm, which can convert the existing two-dimensional (2-D) codes into 1-D codes systematically. The coding method not only improves the encoding efficiency and complexity but also lessens the disadvantage of not generating 1-D spreading codes easily. In addition to the proposed coding construction, the performance analysis of optical code-division multiple-access (O-CDMA) system with the use of proposed 1-D spreading codes and on-off keying (OOK) modulation technique is also provided and validated with computer simulation. Our results show that the proposed codes can provide more flexible design to meet the transmission requirements of different systems indeed.
