communication technologies especially 5G and the future 6G to
deliver ULLC for IoT and auto-mobiles. By the use of simulation
models and real-life examples the research assesses gains resulting
from these next generation networks. The outcome indicates that 5G
network means a set of numerous improvements as compared with
the previous technologies and it possesses the latency of 1. 2
milliseconds and the throughput of 10 Gbps. In the future, 6G
technologies have been expected to increase performance even more
as the forecasted latency of 0. 8 milliseconds, packet loss rates
getting down to around 0. 01%, and throughput which could go to
up to 15 Gbps. The study also presents artificial intelligence, the
edge computing system, and other high-advanced beam-forming
technologies that assist in enhancing network performance and
dependability. Another actual example showed how 5G can be used
in the control of traffic, which reached a latency of 1. 1 millisecond
with the reliability rate of more than 99 %. 98%. Essentially, these
research discoveries indicate how next generation wireless networks
may revolutionize key applications as well as progress the way

The OFDM has advantages of high spectral efficiency and inherent robustness against channel fading so it is used in DVB-T system. The BER performance of the DVB-T in 2K mode for 4-QAM constellations under AWGN, Rayleigh and Rician channel models is analyzed. In this research work, DVB-T system is implemented first using MATLAB and then the MATLAB code is converted into VHDL code using HDL coder according to European telecommunications standards institute (ETSI), EN 300 744 standard. Synthesis and Simulation of OFDM based DVB-T in 2K mode have been carried out using Xilinx tool.

In this paper, we report the performance of orthogonal frequency division multiplexing (OFDM) based DVB-T system for 2k mode under different channels viz. additive white Gaussian noise (AWGN), Rayleigh and Rician with various inputs like Image, audio and video. The transmitted signal is corrupted and is interpreted in terms of different values of Signal-to-Noise ratio (SNR ranging from 0db to 40dB). A 4 quadrature amplitude modulation (4-QAM) scheme is used for the simulation. The results show that the AWGN channel has the lowest bit error rate (BER) under QAM modulation schemes and outperforms marginally over Rayleigh and Rician channels. This can be attributed to the improvement in fading due to multiple reflections received at the receiver. This performance analysis gives the possible scope for improvement in design of advanced version of DVB-T system to support high p...

One way to reduce the high PAPR is by using efficient techniques. In this research, we analyse the PAPR reduction of OFDM signals using SLM and PTS techniques. The input considered for DVB-T system is video signal taken from internet. The simulations of these techniques are carried out using MATLAB.

The OFDM has advantages of high spectral efficiency and inherent robustness against channel fading so it is used in DVB-T system. We investigate the performance of the OFDM based DVB-T systems for 2k mode for 4-QAM in terms SNR, and BER under AWGN, Rayleigh and Rician channels using HDL coder with five input audio and video by simulation. In this research work, DVB-T is implemented first using MATLAB and then VHDL code is generated using HDL coder according to European telecommunications standards institute (ETSI), EN 300 744 standard. Reason for converting MATLAB to VHDL code is less power consumption, MATLAB simulation Validation and floating point to fixed point conversion accuracy. Synthesis and Simulation of OFDM based DVB-T in 2K mode have been carried out using Xilinx tool.

All digital color images contain some degree of noise introduced by the camera when a picture is taken. Image denoising algorithms aim to restore an image in presence of random additive white Gaussian noise (AWGN). Color image denoising is a standard inverse problem. In this paper, an efficient pixel wise weighting techniques for color image denoising based on patch is implemented and simulated using MATLAB tool. The normal, standard and mobile camera color images sets are taken for simulation. Simulation results demonstrate that the WEPLL technique performs well as compared to EPLL technique.

Also directional smoothers useful in motion analysis, edge detection, line parameter estimtion, and texture analysis. Such particular applications require the use of several different angles oriented directional filters. For real time applications, hardware devices having capability of parallel processing can be used. The steerability is the property, in which several filtering operations outputs are linearly combined to achieve output of a directional filter which is arbitrarily oriented. Smoothing filters has a property of steerability, which implies that the outputs of several filtering operations can be linearly combined in order to produce the output of a directional filter at an arbitrary orientation. There are several efficient FPGA implementations of the convolution operation for non-separable and separable have been presented in the literature, research on steerable filter implementations on FPGA is limited. In this paper, we present implementations of steerable Gaussian smoothers using VHDL and simulation is carried out using Model SIM software.

The safety of the vehicle is very significant. This project is designed using GPS and GSM technology and accelerometer. The system contains GPS module, GSM modem, Infrared sensors, DTMF tone decoder, ARM 7 microcontroller, relay switch and accelerometer.GPS system tracks the location of vehicle, GSM system is used for duplex communication. The preventive measures like fuel supply cutoff, engine ignition cutoff electric shock system (installed on steering wheel) and paint spray system are installed in the vehicle which is controlled by user GSM Mobile. Traffic accidents are one of the leading causes of deaths. An important indicator of survival after an accident is the time between the accident and emergency medical personnel dispatched to the accident spot. By reducing the time between an accident occurrence and dispatch of the responders to the scène, mortality rates can be reduced, thereby we can save lives. In this project, the main application is early accident detection and its notification to the concerned emergency Centre. By using accelerometer accident notification can be achieved. Accelerometer can automatically detect traffic accident and immediately notify to central emergency centre, by using GPS coordinates we can reach to the location and rescue one's life. This complete system is designed taking into consideration low range vehicles to provide extreme security to their vehicles and life.
