Let you want to transmit R = 4800 bits/sec information stream from a transmission channel has a bandwidth of 15 kHz. You are allowed to use Nyquist criterion pulses with roll-off factor r = 0 with an orthogonal non-coherent MFSK modulation, (a) (5 pts) Determine the maximum value of M which minimizes the Eb/No at the receiver? (b) (10 pts) The following model for path loss as a function of distance is commonly used for system design. P. = P. (do) where P, is the transmitted signal power, P, is the received signal power, do is the reference distance which is commonly selected as 1 meter, d is the distance between transmitter and receiver (in meters), and y is the path loss exponent (You can assume y = 2). No = 10-4 W/Hz and d = 10 meters, for the above MFSK Using the path loss model, assuming- 2 system what should be the value of P (in dB) so that the BER at the receiver is Py = 10-5. (c) (10 pts) Now, you can use a channel with transmission bandwidth 20 kHz. What is the maximum value of M. For the system given in part (b), determine the value of Pr (in dB) so that the BER at the receiver is P = 10-5. (d) (5 pts) Create a table and interpret your results found in part (b) and (c).
