Maximizing the Average Spectral Efficiency of Adaptive Coded Modulation

Adaptive coded modulation (ACM) is a promising tool for bandwidth-efficient transmission in a fading environment. The main motivation behind employing ACM schemes is to improve the spectral efficiency of wireless communications.
