Abstract
The adaptation of a modulation scheme to changing channel conditions can provide improved average data rates over non-adaptive signaling. In this paper, an algorithm is presented for changing the modulation scheme based on the filter outputs used for demodulation. The number of transmitted bits per symbol is adjusted as a function of the filter outputs. Performance results show that the adaptive scheme outperforms fixed-rate modulation
