+    %VNLE Apply an equalization algorithm to the received signal and calculate BER
+    %   This function takes an equalizer object, a received signal, and the 
+    %   transmitted symbols to apply equalization, map the received signal back to bits,
+    %   and compute the bit error rate (BER).
+    %
+    %   Inputs:
+    %     EQ         - Equalizer object that provides the equalization method
+    %     rx_signal  - Received signal that needs to be equalized
+    %     tx_symbols - Transmitted symbols used as a reference for BER calculation
+    %
+    %   Outputs:
+    %     eq_signal  - Equalized version of the received signal
+    %     ber        - Bit error rate after equalization
+    %     numErrors  - Number of bit errors detected
