These days, computer simulation is increasingly being used for design and performance evaluation of communication systems. When simulating a mobile wireless channel for such systems, it is usually assumed that the fading process is a random variate with Rayleigh distribution. In this paper, we have tried to understand Rayleigh Fading (which best describes the scenario inan urban or macrocell environment) better by comparing different models and observing the changes that are caused by varying different parameters. At present, there are a number of methods to generate the Rayleigh...

Traffic noise pollution is identified or recognised as one of the major environmental pollution in the civilized world. It is important to develop mathematical relationship between traffic noise and traffic intensity or volume in Bangladesh perspective. This work focused on the traffic pattern in Dhanmondi, Dhaka (capital city), Bangladesh. Data was collected, simulated over MATLAB and analysis was done over rush hour/ non rush hour, weekdays/ weekends, etc.
