Performance comparison of HARQ with Chase combining and incremental redundancy for HSDPA
In this paper we compare two hybrid automatic repeat request (HARQ) combining strategies that currently are considered for the high speed downlink packet access (HSDPA) evolution of WCDMA. The two HARQ combining schemes are Chase combining, where the retransmissions are identical copies of the original transmission, and incremental redundancy (IR), where the retransmissions consist of new parit...
متن کاملFast performance prediction of power controlled HSUPA with channel estimation
Transmit power control (TPC) is used in high speed uplink packet access (HSUPA) to compensate for the near far effect which degrades system performance. However, its use in joint application with turbo coding, and hybrid automatic repeat request (Hybrid-ARQ) is very prohibitive and time consuming. In this article, we propose a simplified simulation methodology for power controlled HSUPA with Hy...
متن کاملDetermining the Optimum Threshold Values of MCS Levels for Retransmission Packets in HARQ Schemes
We analyze the optimum threshold value used in determining the modulation and coding scheme (MCS) level of retransmission packets in HARQ schemes. In HARQ schemes, although the first packet is erroneous, it has a considerable energy that can enhance the system performance such as packet error rate (PER) and throughput. Using the existing energy of the first transmission packet, we can save the ...
متن کاملIncremental Redundancy Hybrid-ARQ with Rate Compatible LDPC Codes
Hybrid ARQ (HARQ) is well known link adaptation scheme which improves system throughput combining the error correcting codes and retransmission scheme. The incremental redundancy (IR) HARQ transmits parity bits incrementally when the retransmission is requested and normally provides higher throughput than the Chase combining by adaptive transmission in accordance with channel variations. In thi...
متن کاملS Performance Evaluation of MIMO and HARQ Techniques for LTE Uplink System
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...
