Performance of conventional receiver in a CDMA MIMO system using non classical spread spectrum sequences

摘要

In this paper, we will highlight the role of spread spectrum sequence on the performance of the CDMA MIMO system. Then we will consider a family of sequences generated by non linear system selected according to the criteria maximum pic of periodic (MPPC) and aperiodic (MPAC) correlation. The performance of these sequences were computed and compared to the performance allowed by the classical Gold sequences. Numerical results showed that the use of these sequences improves the performance of conventional receiver.
