Abstract :
In this paper, we present characterization of multipath propagation channel for 2.4 GHz carrier. The effect of relative movement between transmitter and receiver and its effect on channel characteristics in terms of Doppler spread in frequency domain are also discussed. Based upon this, a model is explored, which enable us to map the fading characteristics into the received envelope power and hence a way to estimate maximum Doppler spread is obtained. The variation caused by values of sigma is also estimated. Combining the former two estimations for a fixed received power the graphical relation between sigma and maximum Doppler shift is obtained.
