function [eq_signal,eq_noise,ber,numErrors] = vnle(EQ,M,rx_signal,tx_symbols,tx_bits)
    %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
