AWGN في قناة QAM– محاكاة لتقنية تعديل 16

الملخص

QAM plays an important role in today's communications field, so it is of theoretical and practical important to conduct an in- study of 16- QAM,in this paper, the effect of Additive White Gaussian Noise (AWGN) Channel is simulated on the performance of 16- Quadrature Amplitude Modulation for different values of Eb/No using MATLAB programming. The simulation results show that the simulated bit error rate for 16 - QAM modulation in is good agreement at the value ( Eb/No=-12dB). Keywords- 16-QAM, Simulation, MATLAB.
