Semester 7
Q1) Consider a cellular system with S/I ratio of 18 dB. The frequency reuse factor is N = 7, calculate the worst case for signal-to-co channel interference ratio. It is the frequency reuse factor 7 still being acceptable? If not, what is it? Assume path-loss exponent as 4 in a mobile radio environment
Q2) In a celular system. If carrier frequency fc=900MHz an mobile velocity is 70km/hr. Compare the received carrier frequency if the mobile is moving
i) directly towards the transmitter,
ii) directly away from the transmitter
iii) In a direction which is perpendicular to the direction of arrival of the transmitted signal.
