Question # 1. [Marks 20] a. If 4KHZ voice channel is centered on frequency spectrum at 6KHZ and 1MHZ then which range of frequency will be logically narrower? What is its relationship with antenna size? Describe it mathematically. b. Assume three mobile system providers i.e. A, B and C allocate 30KHZ, 200KHZ and 5MHZ bandwidth respectively, to accommodate a single user. Calculate duration of bit, bit rate and baud rate if BPSK and QPSK modulation technique is used. c. How much transmitting power required to be reduced, if mobile station move 4 times nearer to the base station from the edge of the cell?
