4 (35 pts): Let you want to transmit R₂ = 4800 bits/sec information stream from a transmission channel which has a bandwidth of 20 kHz. You are allowed to use Nyquist criterion pulses with roll-off factor r=0 with an orthogonal non- coherent MFSK modulation. (a) (7 pts) Determine the value of M which minimizes the E/No at the receiver? (b) (8 pts) Based on your result In part (a), determine the value of E/No (in dB) so that the BER at the output of the receiver is P, 10-7. (c) (7 pts) Determine the value of M which minimizes the E/No at the receiver when R₂ = 9600 bits/sec and channel bandwidth of 20 kHz? (d) (8 pts) For the system given in part (c), determine the value of (in dB) so that the BER at the output of the receiver is P. = 107 Then P, 20 M-1 2 P₂ = M/2 -P₂ M-1
