A 4–10 GHz fully-integrated power amplifier (PA) is demonstrated using a 0.15-μm GaAs pHEMT process. This PA employs a compact structure with 4-parallel 3-stacked-FET cells to obtain a broadband power performance within a very small chip size. The measurement results of this PA in the frequency range of 4–10 GHz show a gain flatness of 13.5±1.5 dB, a maximum input return loss (S11) of −9 dB, a maximum...
In this paper, the technology of through silicon via (TSV) is applied to radio frequency (RF) receiver module. A grounded coplanar waveguide (GCPW) with TSV is proposed, through the simulation, and the improvement of TSV on RF transmission performance is studied, including TSV's aperture size, density, arrangement and so on. This paper also studies basic components model such as resistance, capacitance...
The absolute positioning technique based on cross coding inductive loop wire has been recognized as the most suitable one to be applied in medium-low speed maglev train system, and the speed measuring method which utilizes the information collected from the lowest address code line has also been recognized as a reliable way for such system. Consider that cross coding inductive loop wire based positioning...
Pay-how-you-drive (PHYD), which has already been recognized as the most promising differentiated commercial vehicle insurance product in usage based insurance (UBI), can objectively analyze the risk level of each insured vehicle by analyzing its driving style from raw data collected by on-board diagnosis (OBD) module set up on it. Finding certain kinds of driving styles, or risk modes from raw data...
Pay-how-you-drive (PHYD), which is an advanced product form in usage based insurance (UBI) for vehicle, takes not only driving habit and behavior into consideration in its actuary process, but geographical factors, sociological factors, psychological factors, and even meteorological factors as well. PHYD insurance product is supported by refinement and analysis based on raw driving data of insured...
Compressed Sensing (CS) theory has been widely used in radar signal processing field, and the reconstruction algorithm is the key to whether the original signal can be reconstructed from limited observations. However, the existing reconstruction algorithms either don't consider and remove the noise in signal reconstruction, or need the iterative estimation of noise variance during the signal reconstruction...
Compressed Sensing (CS) has been widely used in radar imaging field to reduce the data amount. The measurement matrix has direct effect on the degree of dimension reduction and the quality of target image. However, the measurement matrix is usually chosen as random Gaussian matrix or local Fourier matrix, and the influence from target characteristics to the measurement matrix optimization has not...
In this paper a highly integrated MCP concept apply to MMICs from DC up to Ku-band is presented. This type of package of low-temperature co-fired ceramic system-in-package (LTCC-SIP) with ball grid array (BGA) structures hereby can realize miniaturization, low-weight and multifunction. More than one of the multi-function MMICs are wire-bonding or flip-chip mount on the top of multilayer LTCC substrate...

Spectrum sensing is a fundamental component in Cognitive Radio networks. Some detection methods for spectrum sensing in IEEE 802.22 Wireless Regional Area Networks (WRAN) were proposed. In this paper, a sensing algorithm of wireless microphone signals based on compressive sensing, Fast Fourier Sampling (FFS), is analyzed and compared with the traditional spectrum sensing algorithms. Although the detection...
In LTE Trunking communication system, users move in terms of group to dispatch and execute tasks. eNodeB may turn into hotspot in a short time. In order to balance the system load and reduce call blocking probability, the paper propose a load balancing algorithm with OFDMA technology based on two typical services. When origin eNodeB initiates load balancing mechanism with adjacent eNodeBs, the point...
Segmenting and interesting objects from microscopic images and classifying microscopic images are very important for biomedical researching work, which help diagnosis and further biomedical research. However, conventional approaches don't behavior as well as expected when they are applied to solve the problem. We hence propose two methods, radial basis function neural network with fuzzy initialization...
A stacking ensemble is a collective decision making system employing some strategy to combine the predictions of learned classifiers to generate its prediction on new instances. The early research has proved that a stacking ensemble is usually more accurate than any individual component classifiers both empirically and theoretically. Though many ensemble methods are proposed, it is still not an easy...
An ensemble in data mining is the strategy that combines a set of different classifiers together to generate an integrated classification system to classify new instances. In the early research, an ensemble outperforms any of its individual components. Stacking is one of the most influential ensemble among the proposed ensemble schemes. Stacking applies a two-level structure: the base-level classifiers...
