| Abstract: | In order to restrain the interference of co-channel users in STBC-OFDM system,in this paper,we studied the low-complexity MMSE multi-user detection algorithms and based on the adaptive MMSE Space-time Multi-user detection algorithms,we adopt the lagrange multipliers method and extend the constraint space scheme for decreasing the complexity of system.The simulations show that the proposed detection gives the better performance than the traditional algorithms,and can greatly reduce the inter-user interferenc... |
