Selective retransmission for SISO-OFDM systems proposed in  considers one selective retransmission in the event of failed packet without throughput optimization using norm of subcarrier gain. We survey the data transmission models in a communication system from the viewpoint of reliability: data transmission often fails owing to errors generated by disconnections, noises or distortions in Cited by: It also provides an overview of the analytical models developed to assess the performance of these protocols.
Keywords: protocols, automatic repeat-request, data transfer, performance When data is transmitted through a noisy channel, data communication systems must be able to detect and recover from transmission mueck-consulting.com by: Hybrid automatic repeat request (hybrid ARQ or HARQ) is a combination of high-rate forward error-correcting coding and ARQ error-control.
In standard ARQ, redundant bits are added to data to be transmitted using an error-detecting (ED) code such as a cyclic redundancy check (CRC). Receivers detecting a corrupted message will request a new message from the sender.
Instrumentation and control systems are highly reliant on data communications, so a working knowledge of the latest communications technologies and the essential protocols is essential for anyone designing, specifying or using instrumentation and control systems.
This book is the only title on the market designed specifically for this audience. In packet CDMA data networks like HSDPA, the measure of performance is the throughput. Thus, previous results on reduced-rank MMSE receivers SINR cannot be used directly.
In this paper, we study the throughput of CDMA data networks using reduced-rank MMSE receivers, automatic retransmission request (ARQ) and packet combining. Romano Fantacci, Mean packet delay analysis for the selective repeat automatic repeat request protocol with correlated arrivals and deterministic and nondeterministic acknowledgement delays, Telecommunications Systems, v.9 n.1, p, March Cited by: Performance of a packetized data transmission in cellular CDMA is analyzed in presence of soft handoff and truncated power control.
The combined effects of soft handoff parameters, truncated power control at physical layer and truncated ARQ at data link layer on throughput and delay performance of packet data under a prescribed delay constrain is studied. Truncated power control improves the.
We consider the design of efficient rate-compatible (RC) irregular repeat accumulate (IRA) codes, a subclass of LDPC codes, over a wide code rate range. The goal is to provide a family of RC codes to achieve high throughput in hybrid automatic repeat request (ARQ) scheme for high-speed data packet wireless systems.
We focus on a hybrid design method which employs both puncturing and extending. The search for cost-effective, and flexible means of connecting computers in a localized community has received considerable attention, during the last few decades.
Intrabuilding power lines (IPL) provide a readily available and easily accessed network for data communications within buildings. In this thesis, a new generation of low-cost computer networks using carrier sense multiple access.

There is increase in constellation size compared to uncoded communication, increase in throughput (b/s/Hz), and decline in BER performance due to decrease of d min. Trellis coded modulation (TCM) is used to offset loss resulting from constellation size increase.
TCM achieves this higher gain by jointly using the distance properties of the code Author: Charanarur Panem, Vinaya Gad, Rajendra S. Gad. In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver.
It provides a mechanism for the receiver to control the transmission speed, so that the receiving node is not overwhelmed with data from transmitting node.

Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, not mathematical proofs.
Teaching and. The adaptive spreading factor selection (ASFS) scheme showed outstanding end-to-end throughput, peaking at three times the performance of standalone modems. We expect the ASFS scheme will be a suitable technology for applications requiring high throughput on a multi-hop network.
Full article. We analyze two different approaches found in the literature for throughput maximization of an adaptive transmission system operating over a slowly-varying flat-fading wireless channel with limited channel state information at the transmitter. While both approaches employ a finite number of transmission power levels and capacity-achieving codes, they differ in the number of quantization levels.
