| Abstract(in English) | This paper proposes a novel transmitter configuration that flexibly enhances the scalability for frequency-domain optical code-division-multiplexing(O-CDM)based on electrical-domain spatial code spreading. The transmitter employs dummy data input and pre-biasing circuits. By inputting the dummy data into the transmitter, the total number of multiplexed binary data streams including those that actually accommodate users/services and the dummy streams remains constant. Pre-biasing circuits enable us to achieve high tolerance to multiple access interference by compensating for the nonlinearity of the M-ary modulation and improve the receiver sensitivity. Here, owing to the dummy data input, none of the parameters for pre-biasing need to be changed regardless of the number of users/services. Therefore, the proposed transmitter can flexibly enhance the scalability of the O-CDM. The feasibility of the proposed transmitter is verified theoretically. |
