Document Summary
Monday december 9, 2:50pm - 5:40pm: attempt all questions, all questions are of equal value, open book, open notes, exam. 1: consider the transmission of a bandpass signal having complex envelope. S(t) on a channel such that the received complex envelope is. A mobile station (ms) lies at a distance of 5 km, 10 km and 15 km from three base stations, bsi, i = 1, 2, 3. Bs2 is the serving base station, while bs1 and bs3 are co-channel base stations (co-channel interferers). P (dbm)(d) = p (dbm)(do) 10 log10(d/do) (dbm) where = 3. 5, and p(do) = 1 microwatt at do = 1 km. Each radio link is a ected independent log-normal shadowing with shadow standard deviation. The data rate with 64-qam modulation is 54 mb/s. The power penalty due to the guard interval is to be kept less than 1 db.
