A new convolutional decoding in OCDMA system

2009 7th International Conference on Information, Communications and Signal Processing (ICICS), 2009
The channel mode of OCDMA system is interpreted first. Then a novel decoding of convolutional codes is proposed according to the characteristics of OCDMA system. And the feasibility of this decoding algorithm is proved with several illustrations. Performance of this convolutional decoding is studied compared with the traditional decoding, Viterbi ...

The performance of a novel multirate OCDMA system

SPIE Proceedings, 2005
A novel wavelength-time differential code division multiple access system is proposed for multirate transmission. The system model is given and analyzed. Differential detection can be adopted by assigning two orthogonal codes for one user and using these two codes to encode “1” and “0” with different period, respectively.
