name: QPSK
full_form: Quadrature Phase Shift Keying
context: The bits after CRC attachment are denoted by , where Bi=Ai+Li. The parity bits for the payload are attached at the end of the frame: k = 1, 2, 3, â¦, Ai k = Ai + 1, Ai + 2, Ai + 3, â¦, Ai + LI The parity bits for the frame header and the control frames are attached at the beginning of the frame: k = 1, 2, 3, â¦, Li k = Li + 1, Li + 2, Li + 3, â¦, LI + Ai
description: Quadrature Phase Shift Keying (QPSK) is a method used to transmit data by varying the phase of a carrier wave. It encodes two bits per symbol, allowing for efficient data transmission over radio waves or cables.
explanation: QPSK is classified as a Modulation Technique because it describes a specific process of encoding information onto a carrier wave for transmission. The description emphasizes its role in data transmission and its ability to encode multiple bits per symbol.
