This technical implementation guide covers generating random 0/1 binary sequences and modulating them using 2ASK, 2FSK, 2PSK, and 2DPSK techniques onto higher carrier frequencies. The guide includes code implementation strategies for generating time-domain waveforms for the first 8 bits, creating coherent and non-coherent demodulator block diagrams after Gaussian white noise channel transmission, and deriving mathematical expressions for pre-decision observation values. The implementation explains why certain modulation schemes cannot support non-coherent demodulation and provides comprehensive BER analysis with MATLAB simulation code for different SNR values.
