Reversible data hiding based on hybrid prediction and interleaving histogram modification with single seed pixel recovery

Hao Luo; Faxin Yu; Zhengliang Huang; Hua Chen; Zhe-Ming Lu

This paper proposes a reversible data hiding scheme for natural images. A hybrid prediction mechanism is utilized in order to produce prediction errors as many as possible. The cover image excluding a seed pixel is partitioned into four non-overlapping segments, and four predictors are tailored for each of them. As a result, most prediction errors concentrate around zero in prediction error histogram. Besides, an interleaving histogram modification mechanism is presented such that the capacity is enhanced and easier to be finely tuned in contrast to some previous approaches. Third, a single seed pixel recovery strategy is introduced. Experimental results show the effectiveness of the proposed method.

We propose a temporal coupled-mode theory for the design of microstrip bandpass filters with multi-resonant modes and reveals the mechanism of the filters based on multi-coupling and energy conservation theorem. As an example, the combined effect of the two orthogonal modes in dual-mode filters is analyzed in detail. By simply tuning the coupling efficiencies of the two resonant modes, two K-band integrated microstrip bandpass filters have been designed and demonstrate opposite asymmetric transmission responses. Both simulation and experiment results agree well with the theoretical analysis, which provides a new approach for filter design and optimization.

In this paper, a new capacitance-to-frequency converter using a charge-based capacitance measurement (CBCM) circuit is proposed for on-chip capacitance measurement and calibration. As compared to conventional capacitor measurement circuits, the proposed technique is able to represent the capacitance in term of the frequency so that the variations can be easily handled in measurement or calibration circuits. Due to its simplicity, the proposed technique is able to achieve high accuracy and flexibility with small silicon area. Designed using standard 180xa0nm CMOS technology, the core circuit occupies less than 50xa0μmxa0×xa050xa0μm while consuming less than 60xa0μW at an input frequency of 10xa0MHz. Post-layout simulation shows that the circuit exhibits less than 3xa0% measurement errors for fF to pF capacitances while the functionality has been significantly improved.

In this letter, the design and performance of a Ka-band 5-b monolithic microwave integrated circuit phase shifter is presented. In the 180° phase bit, a developed switched-path-type topology is employed in order to extend the bandwidth and achieve good phase shifting characteristics. The fabricated phase shifter demonstrates an rms phase error of less than 4.7° and an rms amplitude error of less than 0.6 dB over the frequency band from 31 to 40 GHz. The input and output return loss is measured to be better than 9 dB, and the chip size is 2.55 mm <inline-formula> <tex-math notation=LaTeX>

4 - 20 GHz low noise amplifier MMIC with on-chip switchable gate biasing circuit

Wei Chen; Zhiyu Wang; Hua Chen; Zhengliang Huang; Jiongjiong Mo

By expanding the contactless conductivity detection (CCD) technique to contactless impedance detection technique, a new contactless impedance sensor is designed to implement the online measurement for both the conductivity of a conductive fluid and the permittivity of a non-conductive fluid. In the new contactless impedance sensor, a new simulated inductor is developed to overcome the unfavorable influences of the coupling capacitances by impedance elimination principle, and the digital phase-sensitive demodulation (DPSD) technique is adopted to realize the impedance measurement. To verify the effectiveness of the new contactless impedance sensor, simulation experiments (using different resistors, capacitors, and their combinations) and practical fluid experiments (using KCl solutions with different concentrations, eight organic solvents, and pure water) are carried out. The experimental results show that the development of the new contactless impedance sensor is successful and the conductivity/permittivity measurement performance of the new sensor is satisfactory. The maximum relative error of conductivity measurement is 3.1% and the maximum relative error of permittivity measurement is 5.5%. Compared with the conventional conductivity/permittivity sensors, the new sensor can implement the contactless online measurement of both the two electrical parameters of fluid. Meanwhile, the new contactless impedance sensor is suitable for industrial applications and has the advantages of simple construction and low cost.

The Design and Life Test of a Multifunction Power Amplifier for Space Application

Xiuqin Xu; Hui Xu; Yongheng Shang; Zhiyu Wang; Yang Wang; Liping Wang; Hao Luo; Zhengliang Huang; Faxin Yu

Abstract In this paper, a new meshing criterion for the equivalent thermal analysis of GaAs PHEMT MMICs (Monolithic microwave integrated circuit) is proposed. Based on the meshing criterion, an equivalent thermal model of GaAs PHEMTs with remarkably reduced mesh complexity is established, and the simplification of both layout pattern and vias of MMICs are performed. Theoretical analysis is applied for the calibration of the equivalent thermal model. Assisted by the meshing criterion, chip-level simulators are capable to obtain the peak temperature of MMICs without using averaging approximations, and achieve considerably high simulation accuracy. As examples, two MMIC power amplifiers are designed and implemented using GaAs PHEMT process. Thermal simulation and measurement results obtained with ANSYS ICEPAK and infrared thermography, respectively, show high consistency. The proposed meshing criterion can be applied to improve the accuracy of thermal analysis of MMICs, and the obtained precise peak temperature can be used to effectively assess the power threshold of the designed amplifiers in reliability tests.

Blind image watermarking based on discrete fractional random transform and subsampling

Hao Luo; Faxin Yu; Zhengliang Huang; Zhe-Ming Lu

A broadband low-noise amplifier (LNA) MMIC with a novel on-chip switchable gate biasing circuit is proposed. The biasing circuit is able to switch on/off the low noise amplifier and compensate the variation of threshold voltage (Vth) and temperature, hence improving the robustness of the amplifier over a wide operating frequency range. The switching frequency is up to 1MHz, and the fluctuations of on-state quiescent current and power gain of the amplifier are within ±7.9% and ±0.8% when the threshold voltage varies from -0.15 V to 0.15 V. The power gain variation is stabilized within ±1.25 dB by the biasing network, while the temperature changes from -55°C to 125°C. Realized in 0.15 μm E-mode pHEMT technology with size of 2.0 mm×1.3 mm, the LNA provides a typical gain of 24 dB while maintaining input and output return loss better than 10 dB and the noise figure (NF) of the LNA smaller than 1.6 dB from 4 GHz to 20 GHz.

Color Image Encryption Based on Secret Sharing and Iterations

Hao Luo; Faxin Yu; Hui Li; Zhengliang Huang

A new multifunction power amplifier (MFPA) is designed and fabricated for the application of point-to-point K-Band backhaul TR module. A DC temperature life test was performed to model the up-limit temperature effect of the designed MFPA under space application. After 240 hours of 100°C life test, the test results illustrate that the designed MFPA has only slight power degradation at the saturation region without change of the linear gain. The general performance of the designed MFPA satisfies the requirement of the application scenario.
