The QAM signal waveforms may be viewed as combined amplitude (rm) and phase (ϕm) modulation. As described in Proakis ([2]), the signal waveforms may be expressed as sm(t) = Re[rmejϕmej2πfct] = rmcos(2πfct+
Demodulate Noisy 16-APSK Signal Using Simulink This example uses: Communications Toolbox Simulink Apply 16-APSK modulation to a signal of random data. Pass the modulated signal through an AWGN channel. Demodulate the noisy 16-APSK signal. The example reports bit error rate (BER) and symbol error...
Plot various M-QAM constellations to demonstrate the shape depends on the modulation order. Define a vector of vlaues for modulation order, M, from the number of bits/symbol, k. Get k = 1:7; % Number of bits per symbol M = 2.^k; % Modulation order...
Simulations are conducted with MATLAB/Simulink software R2010b for all the modulation strategies. The modeled solar PV panel with the input 48 V, 7 A depicts as the input for the individual inverter stages of CMLI. For simulations, parameters used are, amplitude modulation index ma=1, switchin...
MATLAB Simulink models are formed to generate the multilevel modulation formats, transmission, and detection in optically amplified fiber communication systems. Transmission performance is obtained for the multilevel optical signals and proven to be equivalent or better than those of binary level with ...

This is achieved by using MATLAB/SIMULINK software package. The simulation results give a considerably smaller BER in the Coherent detection method as compared to the Non-coherent detection method at all SNRs. This shows the advantage of using Coherent detector over the Non-coherent detector. 展开...
