Paper Abstract

In this paper the direct spreading/wavelength hopping en- /de-coding scheme for optical code-division multiple access is proposed. The system structure is designed and analyzed. A new code sequence-wavelength hopping extended quadratic congruence for prime code is adopted. It is shown that the code capability can be increased by increasing the number of discrete wavelengths or by employing asymmetric system with different prime numbers for spreading and hopping. The synchronous signal is designed and analyzed. It is very easy for user to decode synchronously. The performance of the system is investigated and it is shown that the en-/de- coding scheme and system structure are feasible.
