Abstract

Spectral Amplitude Coding Optical Code Division Multiple Access (SAC–OCDMA) is an auspicious advancement in an asynchronous environments. In this paper, we have presented an effective Enhanced Quantum Logic Gate (EQLG) code for SAC–OCDMA to improve the code construction, cross-correlation and minimize the noises. The EQLG code contains unitary matrices with minimum overlaps in code spectral wavelengths of various clients. This drops the Multiple Access Interference (MAI) and furthermore EQLG code, provides high data-rate transmission in networks. The development of the proposed EQLG code is depicted in following strides as; at first build a matrix utilizing the estimation of the weight value and the number of subscribers. Based upon that, the number of rows and columns are located in the matrix. Second, each diagonal sequences are computed by using the QLG method. The execution of the recommended EQLG code will be analysed with existing SAC–OCDMA systems in response to Bit Error Rate (BER). The simulations of encoding with 10–60 users with 622 Mb/s data transmission at a BER of 10−9 have been successfully achieved.
