Phase-Induced Intensity Noise Reduction with Improved Group Velocity Dispersion Tolerance in SAC-OCDMA Systems
The demand for efficient optical communication systems has fuelled considerable research in developing techniques for eradicating phase-induced intensity noise (PIIN) in spectral-amplitude coding optical code-division multiple-access (SAC-OCDMA). This paper investigates the use of modified-AND subtraction detection technique to mitigate PIIN in SAC-OCDMA systems. The simulation results show tha...
متن کاملDesign and Demonstration of a Novel Spectral Amplitude Coding OCDMA Code for Suppression Phase Intensity Induced Noise
A new code for spectral-amplitude coding optical code-division multiple-access system is proposed called Random diagonal (RD) code. This code is constructed using code segment and data segment. One of the important properties of this code is that the cross correlation at data segment is always zero, which means that Phase Intensity Induced oise (PII ) is reduced. For the performance analysis, t...
متن کاملAlleviation Noise Effect Using Flexible Cross Correlation Code in Spectral Amplitude Coding Optical Code Division Multiple Access Systems
-A new code for Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) is proposed and is called Flexible Cross-correlation (FCC) code. The FCC code possesses various advantages; including easy code construction using Tridiagonal matrix compared to other SAC-OCDMA codes such as MDW, MQC and MFH, shorter code length and the important properties of this code is the flexible c...
متن کاملNew Approach of Flexible Cross Correlation (FCC) Algorithm for Noise Alleviation on OCDMA Systems
The flexible cross correlation (FCC) code algorithm for optical code division multiple access (OCDMA) systems has been developed. The FCC approach has advantages, such as flexible cross-correlation property at any given number of users and weights, as well as effectively suppressed the impact of phase-induced intensity noise (PIIN) and multiple-access interference (MAI) cancellation property. T...
متن کاملCross Correlation in Phase noise analysis
Phase noise is a property of an oscillator that can extend in magnitude from the carrier of several volts down to a mere nano-volt far from the carrier. In many cases the lowest noise OCXOs, SAWs and other specialty oscillators have carrier to noise ratios in excess of -180 dBc/√Hz. The noise level of these oscillators often extends below that of even the mixers and low noise amplifiers at base...
