  • A.binary phase shift keying modulation
  • B.quadrature phase shift keying modulation
  • C.quadrature amplitude modulation
  • D.all of the mentioned

Answer: D

Correct answer: all of the mentioned

WiMAX adapts its modulation to the quality of the link, using BPSK when conditions are poor, then QPSK, and QAM when they are good enough to carry more bits per symbol. All three are therefore part of the standard.
