Simulation of Single-Carrier Frequency Domain Equalization

This project implements a MATLAB simulation of single-carrier frequency domain equalization (SC-FDE), where system performance is evaluated by adjusting various parameters including equalization algorithms, equalizer length, and equalization coefficients. The implementation typically involves generating modulated signals, adding channel impairments, and applying frequency-domain equalization techniques such as Zero-Forcing (ZF) or Minimum Mean Square Error (MMSE) algorithms. Key MATLAB functions like fft/ifft for domain conversion, awgn for noise addition, and berawgn for theoretical BER comparison are employed. During simulation, Bit Error Rate (BER) versus Signal-to-Noise Ratio (SNR) curves are plotted using semilogy functions to visually analyze and assess system performance. These simulation results provide valuable insights into SC-FDE characteristics, offering guidance and reference for system design optimization, particularly in determining optimal equalizer configurations and understanding performance trade-offs under different channel conditions.
