In amplitude-phase shift keying (APSK), the constellation points are arranged in equally spaced positions on concentric circles with increasing radii. Two arrangements, known as 4 + 12-APSK and 4+12+16-APSK, are shown in Fig. 3.15. There are four parameters that define the 4+12-APSK const...
Please clarify what code you are unable to produce. Is what you showed us just omitting the parts you are having difficulty with, or are you producing error messages when you run, or ??
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 ...
Carrier-Amplitude Modulation There are four types of carrier-modulated signals are suitable for bandpass channels: amplitude-modulated signals, quadrature-amplitude-modulated signals, phase-shift keying, and frequency-shift keying. Reference, 1. <<Contemporary Communication System using MATLAB>> - John G...
Matlab and Simulink have been used in the evaluation and the BER with and without coding has been compared as the data rate was increased from 64 kbps to 2MBps. It has been concluded that when convolutional coding was applied, the BER has could be improved by 0.54 % at 64 kbps, 0.39 ...
This page covers advantages and disadvantages of ASK modulation.ASK stands for Amplitude Shift Keying.Both ASK advantages and ASK disadvantages are covered.
Book2011, Signals and Systems using MATLAB Luis F. Chaparro Explore book 2.13 QAM System A quadrature amplitude modulation (QAM) system is a communication system capable of transmitting two messages m1(t), m2(t) at the same time. The transmitted signal s(t) is s(t)=m1(t) cos(Ωct)...
