Abstract

Wireless technology offers new found freedom and the potential for 'anytime, anyplace' communications. Communication technology requires being sustainable in the sense of efficiency, not only to preserve the information within the quality requirements, but also to express the same contents with the minimum resources. The Code Division Multiple Access (CDMA) is an emerging technology for next generation multimedia information of real-time and non real-time traffic and various multi-source multi-traffic communication environments. Multiple inputs multiple output (MIMO) as an adaptive antenna based technology which can improves the capacity of wireless mobile communication. The combined technique has both the advantages of CDMA and MIMO systems. Below the jamming margin CDMA alone works up to satisfactory level but above jamming margin CDMA along with MIMO may be a better proposition for anytime-anywhere communication.
