The bit rate for a baseband signal is 1.544 Mb/s, and FEC at a code rate of 7/8 is applied before the signal is used to modulate the carrier. Given that the system uses raisedcosine filtering with a rolloff factor of 0.2, determine the bandwidth required for: (a) BPSK, and (b) QPSK.
Explain what is meant by coding gain as applied to error correcting coding. When FEC coding is used on a digital link, a coding gain of 3 dB is achieved for the same BER as the uncoded case. What decibel reduction in transmitted carrier power does this imply?

1. Select the correct statement(s) regarding frequency modulation (FM) and bandwidth. A. Increasing Kvco will increase frequency bandwidth B. the higher the FM index ?, the wider the modulated signal bandwidth C. As baseband signal, m(t) amplitude increase, so does modulated signal bandwidth D. All are correct statements 2. Identify the way(s) baseband signals, m(t), can modulate a carrier wave. a) By changing the carrier amplitude to reflect m(t) b) By changing the carrier frequency to reflect m(t) c) By...
