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
%FFE or VNLE
