As one of the most promising future fundamental devices, memristor has its unique advantage on implementing low-power high-speed matrix multiplication. Taking advantage of the high performance on basic matrix operation and flexibilitys of memristor crossbars, in this paper, we investigate both discrete Fourier transformation (DFT) and miltiple-input and multi-output (MIMO) detection unit in baseband...
Real-time wireless sensor networks in the industrial settings usually consist of tens of nodes. Seldom do we see a network of over 100 wireless nodes. The smaller size is usually sufficient as a typical plane unit is no larger than a football fieldsize, and the critical data points of interest are not many. Webelieve, however, there is need for large scale real-time wireless sensor networks. In this...
Memristor has emerged as one of the most promising candidates for the fundamental device in the beyond-CMOS era. With their unique advantage on implementing low-power high-speed matrix multiplication, memristors have shown great and vast potentiality in many specific applications. This paper, for the first time, investigates the hardware design of DFT using memristors. Two implementations of DFT using...
In this paper, we present an alternative to the enhancement of urban microcellular wireless localization based on aggregate received range and signal power along with the proposed partitioned NLOS bias models. Specifically, we preprocess received measurements as validated measurements and propose a state-space system framework which covers validated NLOS biases by Markov-transitioned multiple models...
A integrated quasi-lumped LOW pass filter (LPF) for Wireless application was designed and fabricated by low temperature co-fired ceramic (LTCC) technology. The circuit is based on the quasi-lumped filter topology, and two transmission zeros were introduced to achieve sharp suppression rate. Three dimensional inductances and capacitances have been investigated and used to design the LPF. The proposed...
Cardiovascular diseases are the most popular cause of death in the world recently. For postoperatives, cardiac rehabilitation is still asked to maintain at home (phase II) to improve cardiac function. However, only one third of outpatients do the exercise regularly, reflecting the difficulty for home-based healthcare: lacking of monitoring and motivation. Hence, a cardio-pulmonary rehabilitation system...
The purpose of this paper is to analyze the EM field distribution in U-home which is a smart home of Kun Shan University. It is apparent that wireless devices in U-home become EM field emitters. This paper states the measurement and the analysis of the EM field distribution generated by those devices. The measurements focus on some popular frequency bands, such as 430 MHz, 900 MHz, 1800 MHz and 2...
MCM (Multi-chip Module) is presently the most effective method for realizing the miniaturization of wireless front-end applications. Filter is one of the most important components in the MCM. In this paper, a novel quasi-lumped band pass filter for wireless front-end was designed and fabricated, adopting low-temperature cofired ceramics (LTCC). The BPF circuit is based on the quasi-lumped filter topology...
Energy harvesting with the piezoelectric cantilever was studied under vibration environment. A theoretical model of piezoelectric cantilever was developed to determine the magnitude of power. The results predicted by the theoretical model were validated by the experimental data. Compared with the rectangular layer piezoelectric cantilever, the trapezoidal piezoelectric cantilever generated higher...
