This model receives the signal sent by the QPSK Transmitter with USRP® Hardware model. An external clock generator can provide a more accurate and stable clock signal than the internal clock in the radio. In this project we implement quadrature phase shift keying (QPSK) end-to-end digital transmitter/receiver. This model shows the implementation of a QPSK transmitter and receiver. Image data is transmitted using OFDM by QPSK, 16-QAM and 64-QAM to show the relative performances in AWGN noise. The decision boundary,.
