In asynchronous environments, the spreading signature generation is one of the main issues for CDMA communication systems. In this paper it is shown that the spectral design of the spreading signature leads to efficient band-limited signals with attractive cross-correlation properties. The behavior of the proposed spreading signals is simulated in a GSM-like multipath environment and it is compared to that of a traditional DS-CDMA using Walsh binary sequences.

Abstract
In asynchronous environments, the spreading signature generation is one of the main issues for CDMA communication systems. In this paper it is shown that the spectral design of the spreading signature leads to efficient band-limited signals with attractive cross-correlation properties. The behavior of the proposed spreading signals is simulated in a GSM-like multipath environment and it is compared to that of a traditional DS-CDMA using Walsh binary sequences.File | Dimensione | Formato | |
