Solve the following problem:
A wire line channel of length 1000 km is used to transmit data by means of binary PAM. Regenerative repeaters are spaced 50 km apart along the system. Each segment of the channel has an ideal (constant) frequency response over the frequency band 0 ≤ f ≤ 1200 Hz and an attenuation of 1 dB/km. The channel noise is AWGN.
a. What is the highest bit rate that can be transmitted without ISI?
b. Determine the required Eb/N0 to achieve a bit error of P2 = 10-7 for each repeater.
c. Determine the transmitted power at each repeater to achieve the desired Eb/N0, where N0 = 4.1 × 10-21 W/Hz.
