Abstract

Long Term Evolution (LTE) is designed as a wireless broadband technology for a last generation of Universal Mobile for Telecommunication System (UMTS) to provide multimedia services for the users. In order to enhance the performance of LTE system with low complexity for the system, this paper submits Hybrid Adaptive Repeat and Request (HARQ) procedure with one retransmitting and Multiple Input Single Output (MISO) technique using two antenna elements at the transmitter side to improve the capability of the system. The results showed that the block error rate (BLER) and the throughput of the system are improved when the HARQ procedure and MISO technique are employed together in a three cases study of the Channel Quality Indicator (CQI) of the user.
