Unformatted text preview: EE 7615 Problem Set # 5 Due: 11,5,10 1) Please attempt each problem on a new page. 2) Show all your work clearly. 1. Binary Data of rate R b = 500 bits/sec. is to be transmitted across an AWGN channel with noise power spectral density S N W ( f ) = 10 5 watts/Hz. The available frequency band is (2500 , 3500) Hz. Find the smallest power P with which bit error probability of P b ( E ) = 10 5 can be achieved using (a) i. Any PSK system (Binary, 4ary, 8ary, etc.). ii. Any FSK system (Binary, 4ary, 8ary, etc.). iii. Any ASK system (Binary, 4ary, 8ary, etc.). iv. Any QASK system (Binary, 4ary, 16ary, etc.). v. Any system whatsoever. (b) Repeat the above assuming that the data rate is R b = 3500 bits/sec. 2. The following signal set is used to transmit binary equiprobable data of rate R b = 1000 bits/sec. across an AWGN channel with power spectral density of N 2 Watts/Hz. (a) Find an orthonormal basis for the signal set and plot the vector representation of the signals....
