一种新型二维光正交码的设计及性能分析
A Novel Two-Dimensional Optical Orthogonal Code Design and Performance Analysis
摘要
Abstract
Under the premise of low Bit Error Rate (BER), in order to obtain larger code capacity, a new two-dimensional Optical Orthogonal Code (OOC) named ESPC/QCHC is constructed with Extend Square Prime Code (ESPC) as time spreading sequence and Quadratic Congruence-Hop Code (QCHC) as wavelength hopping sequence.The cross-correlation mean value is deduced by analyzing the performance of ESPC/QCHC.The word capacity of the code is theoretically analyzed, and the BER of the code is simulated by MATLAB.The results show that lower BER can be achieved by increasing the number of frequencies when the same code weight (or code length) is given.This code has lower BER and larger code capacity when compared with other two dimensional OOC which constructed by the prime number as time spreading sequence.The simulation results in the Optical Code Division Multiple Access (OCDMA) system have shown that the BER performance ESPC/QCHC is better.关键词
