Optical Code Division Multiple Access

Optics and Photonics News, 2003
Code division multiple access (CDMA) allows multiple users access to limited-bandwidth networks. The Defense Advanced Research Projects Agency has launched an ambitious program aimed at demonstrating technology for an advanced network based on optical CDMA.

Photonic code-division multiple-access communications

Fiber and Integrated Optics, 1997
Photonic code-division multiple access schemes have been proposed since the 1970s. Although there are many published proposals for new coding schemes, there are many less experimental verifications of these schemes, even fewer reports of successful data transmission, and no commercial systems.

Code division multiple access using Hermitean codes

Proceedings of 6th International Symposium on Personal, Indoor and Mobile Radio Communications, 2002
Reed-Solomon (RS) codes present some desirable properties that make them useful in the generation of hopping sequences, for frequency hopping code division multiple access (FH CDMA). The algebraic geometric codes include the RS codes as a special case, therefore it is natural to propose the former as a candidate to FH CDMA.

Coded multicarrier code division multiple access

Proceedings of 1995 IEEE International Symposium on Information Theory, 2002
This paper presents a multicarrier signaling technique for an asynchronous direct sequence (DS) code division multiple access (CDMA) system which employs linear convolutional codes to achieve performance gains in excess of path diversity gains realized in conventional single carrier RAKE DS CDMA systems.

Code Division Multiple Access

2002
As already described in section 2.2.3, a direct sequence SS system can provide code division multiple access. This is performed by assigning each user a different code for the spectrum spreading process. Under ideal conditions and if these codes are chosen properly, there will be negligible interference between different users despite the fact that ...
