– The synchronized symbols enter a QPSK Demodulator Baseband block. Hard or soft decisions can be output. Digital Communication Systems Using Matlab And Simulink
– Map each pair of bits to a complex symbol using the QPSK Modulator Baseband block. Set average power to 1. % Compute BER [~, ber(idx)] = biterr(data, rxBits);
– Compare original bits with demodulated bits using the BER Calculator block. Export results to MATLAB workspace using an "To Workspace" block. % Compute BER [~
