Abstract :
ldquoMulti-levelrdquo wavelength-time codes with asymptotic-optimal code cardinality and flexible code length are constructed and analyzed. The codes can be partitioned into multiple levels of codes with different cross-correlation functions, thus supporting the trade-off between code cardinality and performance for different system requirements (e.g., capacity and throughput).
