Construction of optimal optical orthogonal signature patterns for high throughput optical code division multiple access image transmission

It is stated that high throughput optical code division multiple access image transmission need parallel transmission because of the speed limitation of current opto-electronic devices and the high requirement to opto-electronic devices. Aiming at the problem that signature sequences of the parallel transmission system are two-dimensional optical orthogonal signature patterns different from conventional signature sequences and the construction of the maximal capacity of the optical orthogonal signature patterns is lacked now, a novel construction algorithm based on block design is presented. The idea and the procedures of the algorithm are explained in detail. Simulation based on the algorithm is done. The simulating result shows that this algorithm can construct optimal optical orthogonal signature patterns effectively.
