| Abstract: | Multi-user MIMO-CDMA is new technology in MIMO research areas.Capacity and BER performance can be remarkably enhanced in MIMO-CDMA system.Because of high complexity for DSP realization of MIMO system,antenna selection is lowcomplexity alternative for real MIMO-CDMA system.Multi-user MIMO-CDMA antenna selection Sub-system is introduced in the paper.A simulate Model based on frame structure of multi-user MIMO-CDMA antenna selection sub-system for DSP is designed. Performance in different selection rules,such ... |
