This code calculates BER values for 16-QAM in Rayleigh Channel.You can compare the BER plot with the theoretical values from MATLAB BER TOOL.

1) 16-APSK Modulation Simulink Block2) 16-APSK Demodulation Simulink BlockWhen I create this Simulink block that time there is no error but unfortunately when I put this block in the existing 16-QAM or PSK it does not work properly to compare 16-QAM.Please receive my attach 16-apskWhen I run this...

This simulation illustrates the effects of the fixed-pointcomputations on the closed-loop precision for a 16-bits PID controller.The rounding mode, the point where the truncations take place and theformat width for the internal variable have a significant action on theclosed-loop permanent...

This is a simple FFT based beam propagation method for potential-free 1+1+1D Schrodinger equation. The software if flexible and allows to introduce high-order derivatives in the term (very handful if is needed to include dispersion effects). For example, if one desires to solve an equation in the...
