具有吞吐量和时延约束的软件无线电波形部署决策算法

针对当前具有吞吐量和时延约束的软件无线电波形部署决策算法在内存开销方面考虑的不足,提出一个更为通用的波形部署决策系统模型,将波形的处理开销、内存开销和通信带宽开销都纳入到波形部署决策过程中,并设计了一种基于动态规划的波形部署决策算法以最小化波形对平台各种计算资源的占用总和。仿真结果表明,内存对波形部署决策具有重要影响,与未考虑内存开销的解决方案相比,平台支持的平均最大波形数目和平均处理资源利用率均下降40%左右。

A Deployment Decision-making Algorithm for Software Defined Radio Waveforms with Throughput and Latency Constraints

Aimed at the problem that current deployment decision-making algorithms for software defined radio waveforms with throughput and latency constraints had paid little attention to the memory overhead, a more general system model for waveform deployment decision-making was proposed, by which the processing, memory and communication bandwidth were all incorporated in the process of waveform deployment decision-making. Besides, a dynamic programming-based algorithm for waveform deployment decision-making was devised to minimize the sum of various kinds of computing resource occupancies of waveform. The simulation results shown that the memory had important effects on the waveform deployment decision-making; compared with not considering the memory overhead, the average maximum waveform number platform supported and the average processing resource usage both decreased about 40%.
