Simulate the bit error rate ( BER ) of a binary digital pulse amplitude modulation ( PAM ) for differentsituations of bit energy versus noise
Simulate the bit error rate BER of a binary digital pulse amplitude modulation PAM for differentsituations of bit energy versus noise power spectral density EbN Finally, compare theresults obtained through simulation with respect to the analytical results available for this modulationdigital.To carry out the simulation, the following steps must be followed in MATLAB:a Generate a vector of M random bits equally probable using the functionrandi and save them in a variable.b Modulate the bits generated in part a through a binary PAM digital modulation using the functionpammodc Generate a vector of bit energy versus noise power spectral density in dB EbNodB d Add white Gaussian noise to the pulses generated in part b complying with one of the conditionsof EbNodB generated in section c The above using the function wgne Carry out the digital demodulation of the noisy pulses generated in part d using the functionpamdemod and save the estimated bits in a new variable.f Carry out the estimation of the bit error rate for a value of the EbNodB vector generated in sectionc The above, through the biterr function.g Generate the theoretical bit error rate for binary PAM modulation using the following instructionberteo berawgnEbNodBpsk'nondiff'Finally conclude the project by graphing the results obtained in the simulation on the theoretical results insubsection g Both graphs must be in a different color and with a different marker to be able to appreciate the similarity.From the results. Below is an example of the graph of the theoretical results generated by theinstruction of subsection g Use the semilogy function to compare the results.
