This paper introduces the principle of the SVM in a-b-c coordinates in detail. The traditional SVM require a bit of digital logic and computational power to determining the duty ratio of each switch. However, the algorithm for three-phase four-leg inverter in abc coordinates avoids the alphabetagamma transformation, which can make the selection of the switching vectors and calculation of the duty...
In this paper a new method named EV-t is introduced for parameter estimation. The parameters of primary interest are the time delay and direction-of-arrival (DOA). The EV-t method depends on signal subspace of array covariance, and also requires a training sequence corresponding to the desired user to be known. Simulations show the EV-t method does not suffer from a large symbol collection bias, and...
A large number of signal processing researches consider estimating the parameters of unknown signal from sensor arrays. In this paper, the parameter estimation problem is focused on time delay and direction-of-arrival (DOA) in DS-CDMA arrays, here called two-dimensional code acquisition. A new subspace based estimator is introduced with a rigorous statistical analysis. We assume the training sequence...
The attempts to develop a ubiquitous health care monitoring system arisen from the need of automatic real-time medical services for emergent diseases. Besides, the physiological statuses gathered and maintained by this system are very helpful for diagnosis and early warning. To improve the medical services and diagnosis accuracy, a Wireless Health Advanced Mobile Bio-diagnostic System (abbreviated...
