The decoding operation in this example incurs a delay, which means that the output of the decoder lags the input. This section illustrates two possible mappings: 1 binary coding, and 2 Gray coding.

The Modulate a Random Signal example was modified to employ a pair of square-root raised cosine RRC filters to perform pulse shaping and matched filtering. Figure 2. QAM Communication System. Search MathWorks. The filters are created by the rcosdesign function.

    Like all modulation schemes, QAM conveys data by changing some aspect of a carrier signal, or the carrier wave. this code performs the qam modulation for M=4.

    However, for 16 QAM, since it is both phase and amplitude modulations, it is sensitive to amplitude errors and DC offset.

    The most common type of QAM modulation is rectangular QAM, were the constellation points are arranged in a square grid.

    The example uses baseband QAM (quadrature amplitude modulation) as the The code below also creates a stem plot of a portion of the data stream. File Exchange badges are here!
