Abstract :
DS/SS CDMA use unipolar optical orthogonal codes (OOCs) as address sequence, but its code capacity is too limited. In this paper, two FDMA/CDMA hybrid schemes are discussed. The frequency hop/time spread (FH/TS) scheme could lower the Prime sequence´s sidelobes in autocorrelation. A novel en(de)coder for FH/TS schemes is given. It can vary the address easily and does not need a fiber delay line network
