MIMO-OFDM technology make full use of space and spectrum resources, it can exponentially increase the channel capacity, so it is one of the core technology of next generation mobile communication systems. In order to estimate the time domain (or frequency domain) response of MIMO-OFDM systems fast and accurately, the traditional SVD estimator is modified in this paper. To reduce the time to compute...
In order to meet the requirements of the lifespan test of insulating materials under pulsed electrical stress circumstances, a high-voltage high-frequency pulse power supply device of cascaded H-bridge with optical isolation was developed. After studing the pulse parameters with specimen, we should consider the pulse rise time in load condition but not overemphasize the pulse rise time in no-load...
Fixed priority schedulers are widely used for real-time systems, and there were efforts to improve the schedulability. For example, preemption threshold scheduling increases the schedulability by introducing non-preemptiveness during task execution. In this paper, we study another scheduling model that can improve the schedulability of tasks: quantum-based scheduling. When quantum-based scheduling...
