Performance of OFDM in time selective Multipath fading channel in 4G Systems

MATLAB--2015---IEEE CONFERENCE PAPER

In this project we are going to analyze the doppler effect on OFDM system

PSK modulation is considered in this project.

doppler is nothing but the frequency shift caused by the movement of trasnmitter or receiver.

To apply doppler shift on the signal we use  exp(j*2*pi*fd*(0:N-1)/N) 

fd is the Carrier frequency offset caused by doppler

formula for fd = v*fc/c

v is the speed

fc is carrier frequecny

c is speed of light
