Xiao Zhengfeng, Gong Fangping, Luo Zhao, et al. Research on simulation of quasi-synchronous coherent time-spreading OCDMA[J]. 2010,(3):57-59. DOI: 10.13756/j.gtxyj.2010.03.016.
The aperiodic auto-correlation and cross-correlation of LA sequences have a zero correlation zone near the origin.Thus
a quasi-synchronous coherent time-spreading OCDMA system can be realized by applying the LA sequences to the OCDMA system.The beat noise and multiple-access interferences in the system can be cancelled as long as the time delay between the users is controlled within the range of synchronous errors.A quasi-synchronous coherent time-spreading 1 Gbit/s OCDMA system with 16 users and a transmission range of 20 km is simulated
the result of which indicates that the LA code is applicable to quasi-synchronous coherent time-spreading OCDMA systems.
