(b) Consider we wish to transmit at a rate of 64 kbps over a 4 kHz noisy but error-free channel. What is the minimum SNR in dB required to accomplish this?
(c) How is the rate improved if we double the bandwidth?
(d) How is the rate improved if we double S/N?
(e) Now Consider that the above uses QPSK modulation becomes error-prone, what is the minimum signal power that is needed to sustain a data rate of 64 kbps with a BER of 10-5 at 25 degrees Celsius?
