Can anyone tell me what is the difference between normal bit error calculation of 16 qam in matlab and with monte carlo simulation.
Thank you in advance

In normal bit error rate calculation, closed form expressions are used. In monte carlo simulation, simulations contained in MATLAB simulation functions are used for many iterations to study how a model responds with randomly generated inputs. This results in accurate bit error rate calculation.
