QPSK Transmitter with ADALM-PLUTO Radio

Design a QPSK transmitter with an ADALM-PLUTO radio to modulate and transmit "Hello world" messages at a center frequency and a bit rate of 0.4 Mbps, incorporating ASCII character conversion, Barker code for synchronization, and square root raised cosine filtering for over-the-air transmission.

QPSK Receiver with ADALM-PLUTO Radio

Implement a QPSK receiver with ADALM-PLUTO radio System objects to receive, demodulate at 0.4 Mbps, and print the signal in MATLAB^® command line, addressing carrier frequency and phase offset, timing recovery, and frame synchronization.

QPSK Receiver with ADALM-PLUTO Radio in Simulink

Implement a QPSK receiver using the ADALM-PLUTO Radio with Simulink that addresses wireless communication challenges such as carrier frequency and phase offset, timing offset, and frame synchronization. This model demodulates received symbols from the QPSK Transmitter with ADALM-PLUTO Radio model and outputs messages to the MATLAB command line.
