Abstract
An optical frequency-encoded CDMA transmission system is presented in which received optical signals are decoded in the electric part of an optical receiver (12). To that end, the optical receiver (12) has a single photodetector (6) which converts received light into an electric signal, and which is directly or indirectly connected to a decoding unit (9, 10; 13, 14, 15), for recovering the information contained in the characteristic frequency-encoded spectrum.
