Abstract :
We describe the implementation of radio-over-fiber (ROF) techniques with a combination of spectral-amplitude-coding optical code-division-multiple-access (SAC-OCDMA). The architecture of proposed fiber-radio network is presented in details where the radio frequency (RF) modulated signal is up-converted to the spectrum-coded optical carriers. System evaluation is analyzed by deriving the average bit error rate (BER) expression. Gaussian approximation is applied for the noise distribution, taking into account the thermal and phase-induced intensity noise (PIIN) in the receiver. The binary phase-shift keying (BPSK) signal is modulated on a radio frequency (RF) carrier. System evaluations are performed under the condition of different code-types (m-sequence code and SQC code) and code-lengths.
