dedicated classes that are then injected into the main simulator.

-### apps/simulators/PUCCHBLER
-An instance of the *PUCCHBLER* class provides a simulator object for the evaluation of the performance (in terms of BLER, detection and false detection probability, depending on the case) of the PUCCH processors, for PUCCH Formats 0, 1 and 2. The following example shows how to evaluate the PUCCH Format 2 BLER at `SNR = -10:0` dB for the default configuration. For more information, enter `help PUCCHBLER` at the MATLAB command line.
