Principle and Operation of Quadrature Phase Shift Keying Receiver
  • Principle and Operation of Quadrature Phase Shift Keying Receiver

  • Study guide • 3 pages • 2019
  • This article describes, (a) Detail principle of QPSK receiver. (b) It analyzes the operation of QPSK receiver mathematically. (c) Each block of the receiver has been analyzed and explained mathematically. The QPSK receiver, like the BPSK receiver, can create a synchronous carrier when the received signal has a phase shift. Show that even if the signal s(t) is shifted by an angle, the output of the frequency divider produces cosine and sine carrier wave synchronous to the received signal.
