Interference Mitigation in LTE- Advanced MU-MIMO through Beamforming Technique
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 2
Abstract
3GPP LTE advanced is an evolving standard targeting 4G wireless system, LTE-Advanced introduces new functionalities such as Carrier aggregation, enhanced use of multi-antenna techniques. In this work, the different multi-antenna techniques such as single user MIMO (SU-MIMO) and multiuser MIMO (MU-MIMO) cases are investigated. In MUMIMO case, interference is more when compared with SU-MIMO case. To overcome this challenge, the beamforming technique is used under the assumption of perfect channel knowledge at the transmitter availability. We evaluate the system performance of SUMIMO and MU-MIMO cases in the different scenarios, with and without beamforming technique in terms of Bit-Error-Rate (BER) and Signal to Noise Ratio (SNR). For the stimulation purpose we use MATLAB software package.
