Interference Aspects of Adaptive Modems over Slow Rayleigh Fading Channels
, 1999 Adaptive modulation can achieve channel capacity gains by adapting the number of bits per transmission symbol on a burst-by-burst basis, in harmony with channel quality fluctuations. This is demonstrated in the paper for target bit error rates of 1 and 0.

Effective capacity of a correlated Rayleigh fading channel [PDF]
Wireless Communications and Mobile Computing, 2011 AbstractThe next generation wireless networks call for quality of service (QoS) support. The effective capacity (EC) proposed by Wu and Negi provides a powerful tool for the design of QoS provisioning mechanisms. In their previous work, Wu and Negi derived a formula for effective capacity of a Rayleigh fading channel with arbitrary Doppler spectrum ...
