Channel capacity can be increased by using the Spatial Division Multiple Access (SDMA) technique. Smart Antenna Systems are used to implement the SDMA technique in Real-Time and it also helps in finding the high-resolution Direction of Arrival (DoA) detection of the desired mobile users. In this paper novel Gaussian Triangular Factor (GTF) method is proposed for the detection of the desired mobile users from the 3-D spatial domain. This method is based on vector subspaces, which perform the triangular decomposition of the entire Eigenspace into the Lower Element Factor (LEF) and Upper Element Factor (UEF). These are then supplied for the computation of the power spectrum where peaks represent the detected locations of the desired mobile users in the 3-D spatial field. The proposed method was able to detect all the desired users, which were spaced nearer or far apart spatially, it provided high-quality detection regardless of the number of antenna elements used at the Base Station (BS). The GTF Method was able to detect all the desired users under the presence of heavy noise, fading, and interference. It was able to suppress the side lobes, back lobes, and grating lobes thus immensely improving the detection quality, detection range, system power consumption, detection efficiency, and effectiveness. The proposed GTF method was compared with several existing methods and it provided the best results for different performance parameters like Detection Error, Resolution, Time Complexity, and Disturbance Error.

The card transactions have become increasingly omnipresent and so have the dangers to cyber crime. Three major attacks that we go through with the usage of ATM cards is skimming devices, shoulder surfing and fake keyboard. A common problem associated with cyber crime and the blocking of ATM cards is the long and tiring interactions with the company customer services. In this project we are using a three level of authentication factor employing CAPTCHA, Dash Matrix Algorithm and One-time password. There is a NFC card with all the bank details of the customer. With the help of NFC tag in the ATM machine all the information in the tag is identified by the system. Then the data is encrypted and finally a OTP is sent to the mobile of the customer in order to undergo any transactions. This proposed system, therefore, ensures both secure usage of ATM cards and cost effectiveness by utilising a common and user friendly technology.

Every technique can only represent a limited number of users and are prone to errors. Hence, the intention is to combine two modulation techniques: M-ary amplitude modulation technique and the phase-shift keying method such that the number of users can be as many as the product of that which could be accommodated by the modulation techniques each used individually. Wireless energy harvesting happens to be a promising technique for the future. Our scheme is applied to a previously suggested Wireless energy harvesting scheme.

There are often serious discrepancies existing between images and the direct observation of the real scenes. Human perception has natures of dynamic range compression and color rendition on the scenes. It can compute the details across a large range of spectral and lightness variations, thus it is color constant. Single-scale Retinex (SSR) was defined as an implementation of center/surround Retinex. Superposition of weighted different scale SSR balances both dynamic range compression and tonal rendition, which is Multiscale Retinex (MSR). For color images, spatial averages of the three color bands are far from equal, thus the output appears grey. To address this issue, a weight factor for different channels is introduced which is Multiscale Retinex with color restoration (MSRCR). In this paper, SSR, MSR and MSRCR systems for image enhancement are implemented and their performances are compared using MATLAB as the so...
