Abstract

Optical interleave division multiple access (O-IDMA) technique suits best when heavy traffic intensity and greater interfering environment. This technology has proved its supremacy on other existing multiple access technology like CDMA, OFDMA, FHSS etc. Inter-leavers play on major contribution in deciding specific users in multi user detection method. In present article random, tree and prime inter-leavers are used for measuring the efficacy estimation of O-IDMA technique. Convolutional codes, for fixed number of memory units (fixed constraint length) are incorporated in encoder architecture for estimation purpose. The code rate has been changed and BER for different users has been examined for different inter-leavers.
