An OCDMA transmission arrangement involves encoding both first and second nominally orthogonal polarization signals with a same long code, and transmitting the long-encoded first and second nominally orthogonal polarization signals from respective first and second transmission sources to at least one destination. A corresponding OCDMA demodulating arrangement demodulates the first and second nominally orthogonal polarization signals that were transmitted from respective first and second transmission sources after having been encoded with the same long code. The demodulation arrangement involves receiving the encoded first and second nominally orthogonal polarization signals, and applying the same long code to the received encoded first and second nominally orthogonal polarization signals.
L'invention concerne un dispositif de transmission OCDMA impliquant le codage d'un premier et d'un second signal de polarisation orthogonale au moyen d'un même code long, et la transmission du premier et du second signal de polarisation orthogonale codés de la première et de la seconde source de transmission vers au moins une destination. Un dispositif de démodulation OCDMA correspondant démodule le premier et le second signal de polarisation orthogonale qui ont été transmis de la première et de la seconde source de transmission, après leur codage par le même code long. Le dispositif de démodulation implique la réception du premier et du second signal de polarisation orthogonale, et l'application du même code long au premier et second signal de polarisation orthogonale codés, reçus.
