Aimed at the problem that current deployment decision-making algorithms for software defined radio waveforms with throughput and latency constraints were 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. Simulation results show that the memory has an important effect on the waveform deployment decision-making, while comparing with the algorithm that does not consider the memory overhead, the average maximum waveform number and the average processing resource usage supported by platform are both decreased about 40%.
