Abstract:
Long Term Evaluation (LTE) is one of the modern technologies used to provide high quality network and data usage, providing a good service to the user .Many techniques emerged in it, the weak received signal which leads to decrease in the performance of the services offered to the user. The Co-operative virtual MIMO One of the techniques used to improve the quality of network service. This project is based on the study of the CO-operative Virtual Multiple Input Multiple Output (MIMO) for the purpose of analyzing and measuring the performance of the service before and after the use of this technology, in which the study of the fourth generation networks and the developments that took place in it. The CO-operative Virtual MIMO is one of the most promising technologies in the field of communications, By using the number of three Relay and support one user so that this user receives signal from each Relay (receive three signal) and compared with the normal Relay and found that the new technology is the best. The Data and Frequency, and system bandwidth is constant value in simulation code. The MATLAB program was used to measure the performance of the user before the use of the CO-operative Virtual MIMO and the change that occurs after the use of the technology and the results obtained in SINR, DR, TH, SE and DT and enhanced by respectively in 251.69%, 164.07%, 35.29%, 332.2% and 277.2%.
