Question

1. Perform a Monte Carlo simulation of 4-PAM communication system using MATLAB. Perform the simulation for 10,000 symbols and measure the symbol-error probability when $\sigma^2 = 0.5$, where $\sigma^2$ is variance of the additive Gaussian noise. The model of the system is as below: Error counter Compare $A_m$ with $\hat{A}_m$ X Uniform RNG Mapping to amplitude level $A_m$ r + Detector $(0, \sigma^2)$ Gaussian random number generator $\hat{A}_m$ where the amplitude of the $m^{th}$ level is $A_m = (2m - 3)$, $m = 0, 1, 2, 3$ 2. Plot the theoretical symbol error probability versus SNR. Compare the result for $\sigma^2 = 0.125$ to symbol error rate measured from the Monte Carlo simulation.
