Simulate a basic communication system in which the signal is first QPSK modulated and then subjected to Orthogonal Frequency Division Multiplexing. The signal is then passed through an
Visualize signal behavior through the use of eye diagrams and scatter plots. The example uses a QPSK signal which is passed through a square-root raised cosine (RRC) filter.
Use the Complementary Cumulative Distribution Function (CCDF) System object to measure the probability of a signal's instantaneous power being greater than a specified level over its
Use the Parallel Computing Toolbox to accelerate a simple, QPSK bit error rate (BER) simulation. The system consists of a QPSK modulator, a QPSK demodulator, an AWGN channel, and a bit error
