Fasola: The Effect of HARQ Procedure on the Performance of LTE System
نویسندگان
چکیده
In this paper, the parameters of the LTE system in DL are investigated. These parameters include the effect of the Hybrid Adaptive Repeat and Request henceforth (HARQ) on the Signal to Noise Ratio (SNR), Block Error Rate (BLER), and throughput. The paper deals with three cases of Channel Quality Indicator (CQI): 3,7 and 15.The results showed that the HARQ procedure can improve the BLER and the throughput when the retransmission between the evolved base station (eNodeB) and a User Equipment (UE) increased. Keyword:-Channel Quality Indicator (CQI), Hybrid Adaptive Repeat and Request (HARQ), Long Term Evolution (LTE), User Equipment (UE). ةيئارجا ريثات ةداعلاا بلط نيجهلا فيكتملا ماظن ىلع ليوطلا روطتلا دما يتبرشلا يماس سارف ةلوصف ظيفح ناوفص دعاسم سردم دعاسم سردم ءابرهكلا مسق/ةسدنهلا ةيلك تلااصتلاا مسق/تاينورتكللاا ةسدنه لاخا ص ة ريثات ةسارد مت ثحبلا اذه يف تاريغتم ليوطلا روطتلا دما ماظن ريغتملا هذه نمضتت ,لزانلا هاجتلااب ا ريثات ت .قفدتلاو ءاطخلاا لدعمو ءاضوضلل ةراشلاا ةوق ىلع نيجهلا فيكتملا ةداعلاا بلط عت ا لاث عم ثحبلا اذه لم تلااح ث :ةانقلا ةدوج رشؤمل 3 و 7 و 51 ا. نا جئاتنلا ترهظ نيجهلا فيكتملا ةداعلاا بلط اطتسا قفدتلاو ءاطخلاا لدعم نيسحت ع .مدختسملاو ةيزكرملا ةطحملا نيب لاسرلاا ةداعا ةدايز دنع يجهلا فيكتملا ةداعلاا بلط ,ةانقلا ةدوج رشؤم:ةيحاتفملا تاملكلا .مدختسملا ,ليوطلا روطتلا دمأ ,ن Received: 23 – 10 2012 Accepted: 16 – 7 2013 Al-Rafidain Engineering Vol.22 No. 1 February 2014 111

Modeling and Performances Evaluation of HARQ Technique for MIMO Transmission in Downlink LTE Cellular Networks
Long Term Evolution (LTE) is designed for deployment in a variety of spectrum allocation ranging from 1.4 MHz to 20 MHz. The peak data rate envisaged for LTE is 100 Mbps in downlink and 50 Mbps in the uplink. Unfortunately, different constraints have a strong influence on system performance such as the velocity of user equipment and effect of multipath channel. To achieve data rate compliance w...

In order to avoid dropping the periodic CSI report frequently in case of collision between a periodic CSI report and HARQ-ACK feedback in LTE-Advanced system, this paper gives two coding schemes for multiplexing periodic CSI (Channel State Information) with HARQ-ACK (Hybrid Automatic Repeat request Acknowledgement) feedback on PUCCH (Physical Up Control Channel) format 3. The result of simulati...

A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...

In this paper, we carry out a performance evaluation of multiple-input multiple-output (MIMO) and Hybrid automatic repeat request (HARQ) techniques for singlecarrier frequency division multiple access (SCFDMA) of the LTE uplink system. Different MIMO schemes such as singleantenna port (SISO or SIMO), transmit diversity (TD) and spatial multiplexing (SM) are described and simulated. In this pape...
متن کاملOn Rate-Compatible Insertion Convolutional Turbo Codes and HARQ for Mobile Communications
Rate-compatible Turbo codes are part of many mobile communication systems as, e.g., LTE. The code rate of a fixed-rate mother Turbo code is adapted by bit puncturing and bit repetition. While bit puncturing allows to flexibly increase the effective code rate by discarding a certain number of encoded bits, bit repetition facilitates lower effective code rates by duplicating a distinct number of ...
