Optical code division multiple access methods BER measurement in real time environment

The code division multiple access (CDMA) methods are extensively research during the past ten years. In CDMA measurement the real environment was simulated with various mathematical models. Any practical OCDMA system will require real time environment measurements with clock and data recovery (CDR). Performing CDR on OCDMA data and converting OCDMA signal to an NRZ signal will enable interoperability with standard digital circuits
