The document digitization is one of the emerging trends of digitization. The digitization of documents allows retrieving of information from paper document. This information can be ECG, EEG, humidity etc. The document digitization process involves conversion of paper document into image and processing of obtained image to extract information. The digitized signals can be directly applied to present prediction algorithms. As the digitization literature is surveyed, the process of extraction of digital signal from scanned paper document plays very important role in document digitization process. Generally this is done using horizontal scanning. This paper emphasize on use of vertical scanning for extraction of signal trace from paper documents in contrast to horizontal scanning. The vertical scanning method reduces complexity of the digitization process as well as gives accurate digitization.

This paper deals with the modelling and simulation of combined phase and amplitude noise for QAM direct conversion receivers (DCR). We show that, due to phase noise, there is a cross coupling of quadrature component of the signal as well as quadrature component of amplitude noise to in-phase component of signal. Similarly, there is a cross coupling of in-phase component of signal as well as in-phase component of amplitude noise to quadrature component of the signal. Based on the analysis, the symbol error rate (SER) for different levels of amplitude noise as well as phase noise values are presented for M-ary QAM modulation schemes. It is seen that for small phase noise, the SER approaches theoretical SER for only amplitude noise case and increases to large values for large phase noise.

Mine safety monitoring system (MSMS) can achieve a variety of safety factors of production and underground environment such as gas, temperature, humidity etc. for monitoring mine production, safety management and for safety of the miners to provide a good basis for decision making. The number of person injuries and deaths caused by the lack of information in mine are increasing year by year, so it is very important to control the accidents for achieving the safety in process of mine, and the development of the mine industry. At present, the mine monitoring system is generally composed of the monitoring sensor parameters in underground substation, information transmission system and surface base station centre. The communication between the underground substations with the surface centre consists of the information transmitting system that directly effect on the transmission quality of information and investment cost of the system using the Zigbee technology. The purpose of this work is to implement a safety system in mine based on wireless sensor network.

In this paper, a triple band very compact asymmetric monopole antenna with an electrically coupled split ring resonator (SRR) is presented. The operating frequencies cover the worldwide interoperability for microwave access (WiMAX), wireless local area network (WLAN), and Tagometry (Telemetry using RFID) applications. The asymmetric monopole is fed by a microstrip line, whereas the SRR is inductively coupled with the radiating element which gave triple band of resonances. The electric field-coupled SRR yields its resonance at 3.37 GHz in addition to the fundamental wideband resonances obtained by the asymmetric monopole. The simulated operating bands 3.37 GHz, 5.62 GHz, 8.26 GHz are suitable for WiMAX, WLAN and RFID Tagometry bands respectively. The proposed antenna has a very compact size of 12 × 15 × 1.6 mm3 with FR4 substrate. Very good 50 ohm impedance matching of the antenna for all three resonances by getting S11 as -38.5 dB, -39.9 dB, -30.7dB for corresponding three resonance frequencies respectively. Good impedance bandwidth achieved for third resonance 13.74% and desired radiation characteristics of antenna obtained which can use for above noted three applications. The antenna simulations and parametric studies have been done using CST Microwave Studio.

The ever increasing demand for high data rates drives the wireless communication standards towards incorporation of multi input multi output (MIMO) technology. For such systems, the designed antenna must be compact with low profile configuration, good impedance bandwidth and low mutual coupling. In this paper, a compact two-element microstrip antenna operating from 5.8-9.2 GHz is proposed for wireless applications. The simulated antenna resonates at 7.5 GHz frequency, with a 10 dB fractional impedance bandwidth of 45.33% and voltage standing wave ratio (VSWR) of 1.15. The mutual coupling is reduced to around 21 dB at the resonant frequency. For the proposed antenna return loss at 7.5 GHz is 23 dB. The antenna system has a radiation efficiency of 88.16% at the center frequency. The performance of the proposed antenna array is better than the existing microstrip antennas in terms of fractional impedance bandwidth and isolation.

In this paper, we propose a new family of two-dimensional (2-D) codes where one-coincidence frequency hopping code (OCFHC) is used for wavelength assignment and congruence codes (CC) for time slot assignment. The code family possess different maximum cross-correlation values (from 1 to 3) with zero maximum auto-correlation sidelobe value. Ideally, the code with low cross-correlation constraint is a good code but high cross-correlation constraint code can also perform well (under certain conditions). The huge cardinality of the code family suggest their use in multi-rate and multimedia applications with varying quality of service.

The imaging systems like CT, MRI scan exhibits huge amount of digital data and therefore compression becomes crucial for storage and communication resolves. Most of the recent compression schemes offers a very high compression ratio with significant loss of image quality and do not always perform better for all sets of similar images. This work aims at resolving this issue, which serves as the motivation. This paper presents a lossless image compression based on hierarchical extrapolation for medical images using Haar transform and through Embedded Encoding technique. The compression technique proves to be lossless and as well perform better for a variety of images including CT scan, MRI and ultrasound biomedical images than the existing schemes. The performance metrics namely Peak Signal to Noise Ratio, Compression ratio and mean square error values are computed for the compressed image for evaluation. The performance metrics attained through the proposed algorithm is bench marked with JPEG 2000. The result section of this paper brings forth the relative improvement offered by the proposed logic.

Pareto optimal synthesis of aperiodic linear antenna array using cat swarm optimization is proposed in this paper. The synthesis of aperiodic antenna array is a highly nonlinear problem and multi-objective in nature, in which the two dissension parameters like peak sidelobe level (PSLL) and first null beam width (FNBW) have to be minimized simultaneously. To solve the aforementioned problem, multi-objective cat swarm optimization (MOCSO) is proposed to determine the compromised solutions of the dissension parameters PSLL and FNBW by optimizing the antenna element positions. Specific solutions may be chosen from the obtained Pareto optimal set to demonstrate the effectiveness of the MOCSO method over other existed multi-objective methods.
