Abstract :
This paper addresses the issues of MIMO detection schemes for LTE uplink at received port when VMIMO scheme is deployed at transmitter, which is always a trade-off between performance and complexity. More specifically,the authors will focus on the deployment of of virtual MIMO in the UTRA LTE uplink and investigate two different received detection algorithms,namely zero-forcing and minimum mean squared error successive interference cancellation, proposed for V-MIMO detection considering performances and as well as computational complexity.Finally link level simulation results are provided to evaluate algorithms for implementation and feasibility.lt has shown ZF-SIC outperforms somewhat MMSE-SIC in terms of BER under diverse practical scenarios dedicated for LTE systems.
