Abstract

The performance of transmission Multi Input Multi Output (MIMO) beamforming for the multi subscriber in large cell with effective channel throughput has been investigated. The work procedure was based on singular value decomposition (SVD) using Single User (SU) in 3GPP Long Term Evolution (LTE). In LTE Single User – Multiple Input Multiple Output (SU-MIMO) operation mode, the data of a single user is transmitted simultaneously on several parallel data streams, using the available transmission resources, both in time and frequency dimensions. The simulation comparisons with beamforming and without beamforming have been studied for transmission in MIMO modulations. Despite the protection of information in LTE networks have their vulnerabilities. Planned for a more comprehensive analysis of statistical data and based on them to accurately determine the feasibility of using various protective mechanisms 4G networks for different user groups.
