http://ecelabs.njit.edu/ece489v2/lab5.php WebSep 22, 2024 · Using this equation, each symbol in 256-QAM can be used to represent an 8-bit digital pattern (log 2 (256) = 8). Because the M-ary of a QAM modulation scheme affects the number of bits per symbol, the M-ary has a significant affect on the actual data transmission rate. WebDemodulation. In the QAM method, demodulation is the reverse of modulation. Signals from the transmitter side enter the demodulator and get split into two signals which are given to separate mixers. The local oscillator supplies demodulation signals of the required frequency, and the signals produced are in-phase and quadrature signals. mlf shop
