. Consider a mobile communication system using a carrier frequency of 900 MHz. A mobile in this system is travelling at a speed of 40kmph towards the base station in the cell. Calculate the frequency of the received signal. If the mobile user transmits date at rate of 100 Kbps, determine whether the channel is slow or fast fading.
