Q2. An ideal channel has a band-pass frequency response in the frequency range 600-3000 Hz. (a) Design a communication system with 8-QAM signal for transmitting data at 4800 bits/second. For spectral shaping, use a raised cosine spectral characteristic. Sketch a block diagram of the system. (b) Repeat (a) for same bit rate but with QPSK signal and BPSK signal. (c) From answers of (b), do you think that the spectral efficiency is compromised, for a modulation order pre-fixed by protocol/standard, to satisfy Nyquist criterion for zero ISI? Reason properly.
