MATLAB-Based Simulation of Single-Carrier Frequency Domain Equalization

This project provides MATLAB simulation source code for single-carrier frequency domain equalization (SC-FDE). The implementation utilizes MATLAB's signal processing capabilities to simulate SC-FDE techniques for signal equalization. Single-carrier frequency domain equalization is a prominent signal processing method that enhances received signal quality by compensating for channel distortions, thereby improving overall system performance.

The code includes comprehensive implementation of key algorithms such as cyclic prefix insertion/removal, Fast Fourier Transform (FFT) operations for domain conversion, and equalization using frequency-domain channel estimation. Critical functions handle zero-forcing or minimum mean square error (MMSE) equalization techniques to mitigate inter-symbol interference. The source contains detailed inline comments explaining each processing stage - from signal modulation and channel modeling to equalization and error calculation - enabling users to understand and modify the implementation.

This simulation serves as an educational resource for learning SC-FDE principles, demonstrating practical applications in wireless communication systems. Users can experiment with different channel conditions, modulation schemes, and equalization parameters to deepen their understanding of digital signal processing and communication system design.
