AMC and HARQ: How to Increase the Throughput
In this work, we consider transmissions over block fading channels and assume that adaptive modulation and coding (AMC) and hybrid automatic repeat request (HARQ) are implemented. Knowing that in high signal-to-noise ratio, the conventional combination of HARQ with AMC is counterproductive from the throughput point of view, we adopt the so-called layer-coded HARQ (L-HARQ). L-HARQ allows consecu...
متن کاملUsing AMC and HARQ to Optimize System Capacity and Application Delays in WiMAX Networks
The IEEE 802.16 technology (WiMAX) is a promising technology for providing last-mile connectivity by radio link due to its high speed data rates, low cost of deployment, and large coverage area. However, the maximum number of channels defined in the current system may cause a potential bottleneck and limit the overall system capacity. The aim of this paper is to compare the impact on system per...
متن کاملthe present study is a survey os postmodern historical novel with respect to the voice of women. it argues how the recorded history is regulated by the rules of power and how women have been excluded from this discourse.ther study analysez angela carters nights at the circus as an example of postmodern historical novel to illustrate how this novel has questioned the historical narrative and how it has inserted women into history by breaking the rules of patriarchy.
the present thesis is a study of postmodern historical novel with respect to the voice of women. according to postmodern historiography,the established institution of history is one of the other manifestations of patriarchys power which has silenced women. the study analyzes angela carters nights at the circus as a postmodern historical novel which makes its female characters transgress the pat...
15 صفحه اولThe Throughput Performance of LDPC Coded HARQ for MC-CDMA
Broadband packet access techniques will be required for the next generation mobile communications systems. Hybrid ARQ (HARQ) is one of the promising error control techniques. Recently, LDPC coding is gaining much attention. Multi-carrier code division multiple access (MC-CDMA), which uses a number of subcarriers to reduce the ISI resulting from frequency selective channels, has been attracting ...
متن کاملThroughput analysis for W-CDMA system with MIMO and AMC
We evaluated the average throughput of two types of W-CDMA systems with Multiple-inputmultiple-outputand adaptive modulation and coding by numerical simulation and theoretic analysis. One system employs space-time transmit diversity, another implements per antenna rate control. In both systems the modulation levels and Turbo coding rates are dynamically adjusted depending on the channel conditi...
