A compact design procedure and realization techniques of sharp rejection band pass filter with pre calculated feed position is reported in this paper. Two spatially symmetric quadruplets are used asymmetrically with space mapping technique to adjust transmission zeros for getting desired selectivity. External coupling bandwidths are analysed, calculated and plotted for different feed line widths. A set of design equation are proposed to calculate external coupling bandwidths from the physical dimensions of the feed strip. Inter resonator spacing is utilized in special way to enhance overall bandwidth of the filter.

Tracking of object in underwater is a emerging idea. There are several type of approaches used for this but they have high computational complexity. But scientist needs to study fish populations underwater in different environmental conditions. In this paper we proposed a simple algorithm for tracking and detecting multi moving fishes. A huge number of fishes can be tracked by comparing its mean in the successive frame of the video. The obtained output states a measurement of the difference of two mean values. The object window contains the matrix of the intensity value. Then this value is transformed into a set of feature vector. Finally the above two set of features is compared in the successive frame for a good match to its nearest locality. The MatLab 8.0 simulation result shows that the proposed method is capable of accurately detecting with high detection rate as compared to existing approaches with noisy and dense environment.

Ultra-wide band response in planar monopole microstrip antenna is realized due to coupling between fundamental and higher order patch modes. In the reported literature, formulation in resonant length at fundamental and higher order modes of planar monopole patch is not given. In this paper, by studying the surface current distributions for planar monopole rectangular microstrip antenna, a formulation in resonant length at fundamental patch mode for different patch aspect ratio is presented. The frequencies calculated using the same closely agrees with the simulated results. Thus proposed formulations can be used to realize ultra-wide band planar monopole antenna from the desired frequency range.

The coverage and spatial diversity enhancement in the wireless technology needs cooperative relaying strategy. Among a set of N relay elements, the Nth Best-Relay Selection scheme is proposed. The selection algorithm shows improvement in the bandwidth penalty and also increases the spatial diversity by employing a sub-optimal allocation considering the relay relative distance between the source and destination in a multi-hop cooperative systems. A single branch dual-hop network with adaptive Decode-and-forward (DF) and Amplify-and-forward(AF) cooperative diversity systems is considered. The analytical model of the proposed Nth Best-Relay selection scheme over single branch dual-hop system was developed and a closed-form expression was obtained. The BER (Bit error rate) and Outage probability using binary and quadrature phase shift keying modulation schemes (BPSK & QPSK) employing decode-and-forward (DF) and amplify-and-forward(AF) cooperative diversity systems over Nagakami fading channel was estimated. Results show that in the Nth best relay the diversity order is equal to (M - N + 2) where M is the number of relays.
无线技术的覆盖和空间分集增强需要协同中继策略。在一组N个中继单元中,提出了第N个最佳中继选择方案。在多跳合作系统中,考虑到源端和目的端中继之间的相对距离,采用次优分配,提高了空间分集,改善了带宽损失。研究了具有自适应译码转发(DF)和放大转发(AF)合作分集系统的单分支双跳网络。建立了单支路双跳系统第n次最佳中继选择方案的解析模型,得到了该方案的封闭表达式。估计了在Nagakami衰落信道上采用译码前向(DF)和放大前向(AF)合作分集系统的二进制和正交相移键控调制方案(BPSK & QPSK)的误码率和中断概率。结果表明,在第N个最佳继电器中,分集顺序为(M - N + 2),其中M为继电器个数。

In this paper, a constant false alarm rate (CFAR) target detection algorithm is presented. Here, lognormal and Weibull distributions are considered for modeling clutter amplitude of synthetic aperture radar(SAR) images. Then Kullback-Leibler (KL) goodness-of-fit test is employed to evaluate the histogram matching accuracy of estimated probability density functions (pdfs) of selected models with SAR clutter data histogram. With the use of appropriate background clutter model, CFAR detection algorithm is applied to moving and stationary target acquisition and recognition (MSTAR) data. Experimental results demonstrate that, accuracy of CFAR detector is more for Weibull clutter compared to the same for lognormal clutter.

This paper proposes a detection and an estimation of pixels corrupted by impulse noise. A simple and efficient impulse detector known as Min-Max impulse detector (MMID) is utilized for impulse detection. The detector classifies the pixels into noisy and noise free based on the dynamic range of an image. A pixel is identified as noisy if its intensity value coincides with the minimum or maximum value of the dynamic range. The noisy pixels are restored using the median of noise free pixels and noise free pixels are retained as it is. The experimental analysis declares that MMID is good at identifying the pixels corrupted by fixed valued impulses and enhances the performance of a median filter.

Four Wave Mixing, Stimulated Raman Scattering and Amplified Spontaneous Emission Noise tend to belittle the advantages bestowed by WDM transmission link especially in a link containing inline amplifiers. The Non Linear effects have been related with the intensity and thus most of the work has been directed towards the study of input power to depreciate the limitations imposed by the Non Linearities. In this paper a methodology to decrease the combined effect of SRS, FWM and ASE Noise and to minimize the Bit Error Rate has been suggested by optimizing Inter Amplifier Separation for a 10 Gbps WDM system for link lengths up to 500 Kilometers using Simulation. Optimization of interamplifier separation improves the BER and thus the system length can be extended. Also the nature of ASE and FWM effects has been studied and it has been shown that the system performance is most affected by the FWM effect.

Synthesizer phase noise and settling time of RADAR transmitter impacts performance of the radar system. Ability to detect moving-target signals superimposed with clutter depends on spectral purity level of the transmitter signal i.e. phase noise combined with other spurii. Lower the phase noise, stronger the ability to detect moving-target signals. Low time jitter/phase noise clock signals in receiver are enhances dynamic range by increasing SNR. Frequency agile RADARS works at higher bandwidths and narrow channel spacing with fast settling time. Combined PLL&DDS synthesizers and transistor multiplication methods are used for transmitter Local oscillator and Receiver clock signals generation respectively. This paper presents, generation of ultra low phase noise signals with fast settling time using minimum hardware. Measured results taken from in-house developed multi source synthesizer for frequency agile RADARS.

A novel dual band monopole antenna suitable for Multiple Input Multiple Output (MIMO) system is proposed for next generation mobile communication. A simple F-shaped monopole antenna resonates at 2 frequency bands. The proposed antenna covers frequency bands including Wireless radio and Wi-MAX applications with reflection coefficient below -10 dB centred at 1.25 GHz and 5.8 GHz. A parasitic element is introduced in between the two antennas to reduce the mutual coupling between them and thus, enhance the isolation. The proposed antenna is simple to design and with good performance in terms of reflection coefficient, gain and isolation, VSWR.
