摘要：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 MU- MIMO 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 SU- MIMO 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.
