OFDM Adaptive Algorithms Optimize Bit and Power Allocation Based on Channel Conditions

OFDM adaptive algorithms dynamically allocate bits and power according to real-time channel conditions to effectively reduce bit error rates. This comprehensive MATLAB implementation integrates iterative water-filling, CHOW, FISHER, and H-H algorithms alongside an enhanced iterative water-filling variant. Comparative analysis demonstrates that the improved algorithm maintains comparable effectiveness to standard iterative water-filling while achieving superior computational efficiency and practical applicability. Key features include channel state estimation modules, adaptive modulation controllers, and convergence optimization techniques.
