研究目的
To propose an adaptive optimal shaping gain selection method based on Huffman coding to improve the transmission performance of the system, increase the shaping gain, and approach the Shannon limit.
研究成果
The proposed adaptive optimal shaping gain selection method improves system transmission performance and shaping gain, approaching the Shannon limit. It demonstrates advantages in transmission capacity and performance over traditional methods, especially at high SNR where λ=1/70 provides the maximum shaping gain.
研究不足
The method requires finding the optimal λ under different SNR, which involves traversal and calculation, potentially increasing complexity. The practical implementation may face challenges in dynamically adjusting to varying SNR conditions.
