The two bit streams would typically be band limited and or pulse shaped before reaching the modulator. A block diagram of such a system is shown in Figure 2 below. QAM becomes QPSK: The QAM modulator is so named because, in analog applications, the messages do in fact vary the amplitude of each of the DSBSC signals. Quadrature amplitude modulation Quadrature amplitude modulation (QAM) is the name of a family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information. It conveys two analog message signals, or two digital bit streams, by changing (modulating) the amplitudes of two carrier waves, using the amplitude shift keying (ASK) digital modulation ... In QAM (Quadratrue Amplitude Modulation) is The block diagram of 8 QAM modulation consists of : 1 Bit splitter which convert series data to parallel date, in our case there are 3 bits, therefore the output data will be 1 3 of the input signal . * The output of bit splitter will be in three channels (I,Q,C), each channel will transmit one bit . M ary Quadrature Amplitude Modulation EECS 690: M ary Quadrature Amplitude Modulation. ... Using blocks from the SIMULINK Block Library, the Signal Processing Blockset, and the munications Blockset, design a MQAM modulator, patterned after the one shown above, to meet the following specifications: ...
