Resource Overview

This primary simulation code, titled "Comparison of Equalization Schemes," implements modular functions to calculate bit error rates (BER) for various equalizer types. The implementation includes Time Domain Equalizers (TDE) employing Minimum Mean Square Error (MMSE) and Zero Forcing (ZF) algorithms, Time Domain Decision Feedback Equalizers (DF_TDE), and Linear Frequency Domain Equalizers (FDE) with MMSE/ZF variants. Each function incorporates channel modeling with QPSK modulation over tapped-delay-line channels with additive white Gaussian noise.

Detailed Documentation

The core simulation package, named "Comparison of Equalization Schemes," employs dedicated computational functions to evaluate Bit Error Rate (BER) performance across multiple equalization techniques. The implementation systematically compares: Time Domain Equalizers (TDE) using Minimum Mean Square Error (MMSE) and Zero Forcing (ZF) criteria, Time Domain Decision Feedback Equalizers (DF_TDE) with feedback filtering components, and Linear Frequency Domain Equalizers (FDE) implementing both MMSE and ZF algorithms through frequency-domain processing. The simulation framework utilizes QPSK modulation symbols transmitted through tapped-delay-line channel models with additive white Gaussian noise (AWGN) impairment. While designed as an integrated comparison toolkit, each modular function maintains standalone utility for incorporation into other communication system simulations.

With warm regards,
