Main Function Implementation for AAF and DAF Cooperative Diversity in Rayleigh Channels

This main function source code implements the cooperative framework between Adaptive Amplify-and-Forward (AAF) and Decode-and-Forward (DAF) diversity schemes in Rayleigh channel environments. In wireless communication systems operating under Rayleigh fading conditions, AAF and DAF represent two fundamental signal processing techniques where AAF amplifies and retransmits received signals while DAF decodes and re-encodes signals before forwarding. The coordination between these approaches significantly improves signal reception quality and overall system performance by leveraging complementary diversity gains. The implementation showcases how to establish cooperative operation between AAF and DAF protocols within specified Rayleigh channel conditions. The code structure includes channel modeling modules, signal amplification/decoding handlers, and diversity combination algorithms. Key functions handle channel coefficient generation, signal-to-noise ratio (SNR) calculation, and adaptive switching logic between AAF and DAF modes based on real-time channel state information. This practical implementation provides insights into applying these techniques effectively in wireless communication systems, with particular attention to performance optimization through intelligent cooperation mechanisms.
