Enhanced Version of Digital Predistortion Function Simulation

This is an enhanced version of a MATLAB program for simulating digital predistortion functionality. The program models signal distortion during transmission and applies digital predistortion techniques in signal processing to compensate for such distortions. The implementation leverages polynomial-based distortion models and adaptive filtering algorithms to iteratively optimize predistortion parameters. Beyond core functionality, the program includes additional features such as:

- Custom signal input and output configurations, supporting various modulation formats and signal types through programmable interface functions

- Graphical interface visualization of signal processing results, including constellation diagrams, spectrum plots, and error vector magnitude (EVM) displays using MATLAB's plotting capabilities

- Detailed reporting of signal processing outcomes, generating comprehensive performance metrics and analysis reports through automated data logging functions

This enhanced MATLAB program aims to support learning and research in digital signal processing by providing practical implementation examples of predistortion algorithms and system performance evaluation tools.
