Analyze bit error rate (BER) performance of communications systems

The **BER Analyzer** app calculates BER as a
function of the energy per bit to noise power spectral density ratio
(E_{b}/N_{0}). Using this
app, you can:

Plot theoretical BER vs. E

_{b}/N_{0}estimates and upper bounds.Plot BER vs. E

_{b}/N_{0}using the semianalytic technique. The semianalytic technique estimates BER performance by using a combination of simulation and analysis. Use this technique when the system error rate is small, for example, < 10^{–6}.Estimate BER performance by using MATLAB

^{®}functions or Simulink^{®}models.

MATLAB Toolstrip: On the

**Apps**tab, under**Signal Processing and Communications**, click the app icon.MATLAB command prompt: Enter
