A CPW fed ultra wideband (UWB) antenna which is working on the bandwidth 0.2GHz-3GHz with two narrow-band suppression is presented in this paper, and there are some analysis using characteristic mode theory. The antenna is a compact printed monopole antenna, and it produces narrowband suppression through the embedded split-ring resonator and U shape slot in the radiation patch. The simulation results show that, in addition to the specific stop-band frequency, antenna voltage standing wave ratio (VSWR) is less than 2:1 within the scope of the whole working bandwidth. Therefore, the antenna designed in this paper has good application prospect.

In order to meet the requirements of storage and processing capability in satellite, a generation and update algorithm of routing table is proposed in this paper. The routing computation of satellite network is completed by the onboard router and the ground router, and there are two routing tables, which are local-network routing table and whole-network routing table. The analysis and discussion results show that the proposed algorithm can reduce the processing requirements of satellite, and relieve the burden of inter-satellite links. The ground routers can also be upgraded along with the satellite network expansion.

Matching precision is very important and difficult in accurate photography, remote sensing and 3D reconstruction. After analyzing the advantages and shortcomings of current matching algorithms and the epipolar geometry, a new matching algorithm based on global viewpoint difference rectification for framework imagery is devised. Without the aid of orientation parameters, this algorithm contains three parts, the scale rectification for an overall comfortable of the image, the viewport rectification for compensating the bias between the vertical plane of the primary optical axis and the main plane of the scene, and the consistent transformation of two images with different viewports.. Following, the details of the implementation of our methods are also given. The validation experiments of the matching precision show that, the new algorithm can improve the precision dramatically, which is better than many other good matching algorithms.

A novel dual-band bandpass filter (BPF) with high isolation between the two passbands and good selectivity is proposed in this article, which is based on hybrid-coupled microstrip open-circuited stub/split-loop slot multi-bandgap resonator. Based on full-wave electromagnetic (EM) analysis, the proposed filter is found to have the advantage that the both passband central frequencies can be flexibly controlled by the geometric dimensions of multi-bandgap resonator, while the pass-band bandwidths are mainly determined by the cascaded number of the hybrid microstrip/slot resonators. Theoretical prediction is verified by the experimental result of the proposed dual-band BPF.

In this paper, a monolithic 220GHz Voltage-Controlled Oscillators is presented by using 0.5μm InP DHBT technology. Oscillator designs are based on a differential series-tuned topology. The varactor of the Oscillator is achieved by a HBT transistor whose base connects with the collector. The simulated output power is -2.4 dBm. Due to the selection small capacity of the transistor, the oscillation frequency can be tuned between 221.3 and 221.9 GHz when the tuning voltage is between 0 and 2V. A phase noise of -92 dBc/Hz is achieved at 10MHz offsets. The chip area is 0.87mm×0.61mm.

Mihcak et al. proposed a locally adaptive window-based denoising method using maxsimum likelihood (LAWML) with low complexity. However, LAWML was based on decimated wavelet transform (DWT) without taking account of the interscale dependencies. In this paper, we propose a variant of LAWML, namely MPLAWML, based on multiscale products. We improve LAWML by extending DWT to undecimated wavelet transform (UWT) and multiplying the adjacent wavelet subbands to exploit the wavelet interscale dependencies. In the multiscale products, edges are enhanced and noise is weakened. Thereafter, a product threshold is calculated for each product subband and is used on the products coefficients to identify significant features. Then LAWML is applied to process those wavelet coefficients, which are greater than the corresponding products thresholds. Experiments show that the proposed algorithm has more robustness to noise, achieves better visual effects than LAWML and has competitive performance compared with the state-of-the-art wavelet-based denoising algorithms.

As to the existing methods for the modulation in the digital communication field, a new hybrid modulation method based on the frequency and phase is presented in this paper. In the signal modulation process, two different sequences are transmitted and then converted into the baseband signal using the Pulse Amplitude Modulation (PAM). The baseband signal are imparted to a carrier wave by varying the phase and frequency of carrier respectively, so that the modulated signal's phase and frequency have the information of baseband signal. In the signal demodulation process, recover the baseband signal through different demodulation algorithm for phase and frequency. From a large number of simulations, the presented method greatly improves the bandwidth efficiency by transmitting two different sequences effectively under the same bandwidth.
