Assignment:
A digital communication system transmits binary data using polar NRZ pulses of current over a baseband link with a bandwidth of 20 kHz. The transmitter and receiver have ideal "Root Raised Cosine" (RRC) filters with roll off factor = 0.5.
a. What is the minimum bandwidth that the link must provide to avoid generating ISI (inter symbol interference) at the receiver?
b. What transfer function must the link have over this bandwidth to avoid the generation of ISI?
c. A radio link has a bandwidth of 15 kHz. What is the maximum bit rate at which binary data can be transmitted without ISI if the transmitter and receiver have ideal RRC filters with roll off factor = 0.5 using BPSK modulation?
d. What is the noise bandwidth of the receiver?
e. What is the requirement for the phase response (transfer function) of each of these links to avoid distortion of the transmitted waveform?
Provide complete and step by step solution for the question and show calculations and use formulas.
