介绍了GPRS移动通信中动态链路自适应的原理,并研究了静态链路自适应和动态链路自适应算法。对基于误块率(BLER)估计值的链路自适应算法进行了改进,并在GSM/GPRS网络仿真系统中加以实现。最后对仿真结果进行了分析。分析表明,动态链路自适应算法可以使GPRS系统在吞吐量和误块率方面获得更好的性能。
This paper introduces the principle of dynamic link adaptation in GPRS mobile communication and studies the static link adaptation and dynamic link adaptation algorithms. The link adaptation algorithm based on Block Error Rate (BLER) estimation is improved and implemented in GSM / GPRS network simulation system. Finally, the simulation results are analyzed. Analysis shows that the dynamic link adaptation algorithm can make the GPRS system get better performance in terms of throughput and block error rate.
