The investigation was performed with matlab programming accelerometer placed on matlab programming falling mass of matlab programming Marshall Hammer and acceleration data was stored and analyzed. Data got from matlab programming accelerometer was filtered and matlab programming asphalt mix response after each . The purpose of this task is to show matlab programming idea and feasibility of an OFDM system, and investigate how its performance is changed by varying a few of its major parameters. This objective is met by developing matlab MATLAB application to simulate matlab basic OFDM system. From matlab programming technique of this development, matlab programming mechanism of an OFDM system can be studied; and with matlab accomplished MATLAB program, matlab programming characteristics of an OFDM system can be explored. The goal of this task is to show matlab programming idea and feasibility of an OFDM system, and examine how its performance is changed by various some of its major parameters.
