The spectral efficiency achievable by four SAC codes such as Hadamard, modified quadratic congruence (MQC), balanced incomplete block design (BIBD) and zero cross-correlation (ZCC) is evaluated and compared against the number of active users and code length for a bit error rate (BER) of 10 -10. Analytical results indicated that ZCC code can support more users and leads to the best achievable spectral efficiency than other SAC codes considered. Moreover, the effect of shot and receiver thermal noise degrades the SAC-OCDMA system performance, e.g., when the number of users equal to 80, ZCC has 1.8 dB spectral efficiency penalty by considering these noises as additional to intensity noise. 2012-04-10T13:03:25Z 2012-04-10T13:03:25Z 2011-09-25 Working Paper p. 218-222 978-1-4577-1418-4 http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6108702 http://hdl.handle.net/123456789/18755 en Proceedings of the Symposium on Industrial Electronics and Applications (ISIEA) 2011 Institute of Electrical and Electronics Engineers (IEEE)
