Abstract

Optical interleave division multiple access technology (IDMA) is used in recent communication system to cope up with higher code rate, longer traffic intensity as well as superior interference rejection capability. In present article the qualitative performance of OIDMA is analyzed using random and tree interleavers and optimum selection of interleavers are decided by comparing BER performance of random and tree interleavers. Convolutional coding technique is used here for error correction purpose. Code rate has been changed by varying number of Ex-OR gates in encoder design. The memory elements which decides the constraint length is kept fixed. Code rate variation of fixed constraint length convolutional code has been incorporated in encoder design and effect of qualitative performance of OIDMA has been observed and BER is calculated for different users.
