Direct Sequence CDMA (DS-CDMA) uses unique signature for each user to distinguish the information signals belonging to one user from another user. While orthogonal signatures that give values of zero for the cross correlation of different user signatures are highly desirable, only few of these kind of signatures are available. In this paper, the properties of Finite-Time Altered Sinusoidal Signals as orthogonal signatures for multiple access communication are presented. The effectiveness of this type of signature in combating multiple access interference was also evaluated and compared with the performance of the Legendre Polynomial and Walsh-Hadamard Signatures. The results obtained have been favourable. The Altered Sinusoidal Signature is a good candidate for application in DS-CDMA communication and wire line communication systems. |
