• Digitizer and modulation combinations

  Cn = 2 * 20000 * lg(4) = 80000 bits/second C. 8-Ary PSK : It has eight symbols. Cn = 2 * 20000 * lg(8) = 120000 bits/second D. 8-Ary Quadrature modulation : It has sixteen symbols.

• Nyquist Bandwidth

  Thus 8-PSK is often omitted from standards and, as seen above, schemes tend to 'jump' from QPSK to 16-QAM (8-QAM is possible but difficult to implement).

• Digital Communications

  Answer: 64-QAM: M = 64 symbols N = 6 bits/symbol Spectral efficiency = 64/6 = 10.67 bps/Hz QPSK: M = 4 symbols N = 2 bits/symbol Spectral efficiency = 4/2 = 2 bps/Hz 8-PSK: M = 8 symbols N = 3 bits/symbol Spectral efficiency = 8/3 =

• Select the best modulation/coding scheme for a target BER.

  Then, the m = log2M coded bits are mapped to one modulation symbol according to M-PSK modulation scheme. At the receiver side, the received M-PSK symbol is converted back to bits. Let the channel be AWGN.
