In the given text: The primary code used is called the "comparison of equalization schemes". This code utilizes separate functions to calculate the bit error rate for different types of equalizers. Specifically, it includes the time domain equalizer (TDE) with minimum mean square (MMSE) and zero forcing (ZF) algorithms, time domain decision feedback equalizer (DF_TDE), and linear frequency domain equalizer (FDE) with MMSE and ZF algorithms. The simulations involve the use of QPSK symbols and a tapped delay line channel with white Gaussian noise. While these codes are considered as a package, each individual function can be beneficial for other simulations as well.
With warm regards,
