There are two types of hybrid arq schemes ( h - arq ) , type - i and type - ii 目前主要有两种混合arq体制，分别为型h - arq体制和型h - arq体制。
These are only intended for determining the reliability of the transmission , as if it was a pure arq scheme 如果收端要求重传，则发端再发送用于纠错的校验信息。
A lot of arq schemes have come into being , and they have different characteristics in terms of com - plexity and throughput 当前harq中存在的主要问题是复杂度过高，这对高速数据通信极为不利。
Automatic - repeat - request ( arq ) , which helps transmit data at very low error rate , has been proposed to combat the bad channel 自动请求重传( arq )技术，特别是混合arq ( harq ) ，在提高传输的可靠性方面发挥了巨大的作用。
The arq function recovers lost packets by resending the same packets , buffered in the encoder , which helps to avoid a picture collapse Arq功能恢复失去的ip讯息下，这是通过在编码器缓冲讯息并再次发送失去的部份来实现的。
In the thesis , the following aspects are implemented . propose the research progress of h - arq and express the packet combing techniques in h - arq schemes 论文主要完成了以下工作：给出了h - arq体制的研究进展，介绍了h - arq体制中用到的包组合技术。
In order to improve the transmission reliability of data and image in 3g , the channel coding technology - harq combined by arq and fec is often adapted widely 为了提高第三代移动通信中数据和图像的传输可靠性，常采用arq和fec相结合的harq信道编码技术。
Hybrid techniques that combine fec and arq are generally considered to be the best error - control techniques , and may provide much reliability than fec and high throughout than arq Fec和arq的适当组合将提供比单独fec系统要高的可靠性，而且提供比单独arq的系统更高的通过率。
Offers such standard features as qos quality of service technology including proprietary adaptive rate control and real - time auto repeat request 像sony其他会议系统一样， pcs - tl50提供诸如包括专有的适应率控制arc和即时汽车重复要求arq的qos服务的品质技术这样标准的特性。
