'Persian Code': A new orthogonal spreading code generation algorithm for spread spectrum CDMA systems

A novel approach for generating spreading chip codes in code division multiple access (CDMA) systems is presented in this paper. Orthogonal spreading codes can be utilized for secure communication and multiple access to the shared bandwidth. Previous approaches cannot provide both "auto-correla...

Summary:A novel approach for generating spreading chip codes in code division multiple access (CDMA) systems is presented in this paper. Orthogonal spreading codes can be utilized for secure communication and multiple access to the shared bandwidth. Previous approaches cannot provide both "auto-correlation" and "cross-correlation" characteristics while generating desirable number of orthogonal codes with appropriate length. The proposed algorithm provides both auto and cross coloration while crossing the limit of number of available orthogonal codes. Simulation results justify the ability of the proposed algorithm to provide orthogonal codes even in low SNR scenarios.
