This paper proposes a modified discrete Fourier algorithm for parameter estimation of sinusoidal signal with decaying direct current (DC) offset. First, the sinusoidal signal parameter estimating error caused by the decaying DC offset in traditional Fourier algorithm is analyzed. Then, by carrying out discrete Fourier transform (DFT) twice every half a period on the sinusoidal signal which is affected...
Energy consumption is one of the key issues in real-time system scheduling. In this paper, a new low power algorithm (LPABOBF) is proposed for the periodic task model of real-time systems. The algorithm uses dynamic voltage scaling (DVS) to calculate the optimal static speed at the offline stage, and updates the processor speed at running time by using the slack time of both high priority tasks and...
