| ABSTRACT |
Modified Double Weight (MDW) code is a DW code family variation that has variable weights of greater than two. This code possesses numerous advantages including the efficient and easy code construction, simple encoder/decoder design, existence for every natural number n, ideal cross-correlation ( _5;c= 1) and higher SNR. Novel MDW-OCDMA code. New encoder-decoder design using FPGA board as code generator. Large cardinality for BER below 10-9. Fast optical switching and low cost.
