Abstract
The growth of wireless networks in recent years coupled with applications demanding high data rates underscores the fact that the communication system is bandwidthand power-limited. Therefore, an efficient utilization of the radio spectrum is of paramount importance, particularly in developing bandwidth- and power-efficient communication systems. Adaptive transmission has emerged as a viable approach to boost transmission rates in a communication system. Adaptive transmission refers to signaling strategies that adapt some combination of the modulation, transmit power, and coding scheme in response to channel variations. This is rather different from the traditional design methodology, where a transmission power margin is provided to ensure reliable communication in the event of a deep fade. The significant spectral efficiency gains provided by adaptive modulation and coding (AMC) has resulted in its adoption in current and proposed wireless standards including the wideband code division multiple access
