Design and development of a QPSK modulator

Citation

Abstract

QPSK or Quadrature Phase-Shift Keying is a higher order modulation scheme used in digital modulation. In this project, we will be implementing a QPSK modulator for a wireless communication link. The carriers will be chosen as orthogonal frequencies to reduce the bandwidth of the output signal. Later the design will be simulated by PSPICE and will be fabricated on a PCB. The output signal waveform will be measured and tested to find the signal quality and the SNR or Signal to Noise Ratio.
