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 study the effect of Hybrid Adaptive Repeat and Request (HARQ) procedure with multiple antenna technique on the performance of LTE system, this paper deals with HARQ procedure in case of one and two retransmitting. On the other hand, this paper submits Multiple Input Single Output (MISO) technique using two antenna elements at the transmitter side to improve the capability of the system with low complexity for 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. The results explained that the amount of improvement which offered by the procedure of HARQ with two retransmitting be very slight compared with the case of one retransmitting.
