Traditional fading mitigation techniques are designed relative to the worst-case channel conditions, resulting in a poor utilization of the spectrum and the available power a good percentage of the time. In contrast, we introduce and investigate in this paper new adaptive modulation and diversity combining techniques that jointly select the most appropriate(More)
Both adaptive modulation and diversity combining represent important enabling techniques for future generations of wireless communication systems. In this paper, capitalizing on recent developments in adaptive combining, we propose two joint adaptive modulation and diversity combining (AMDC) schemes. With these schemes, the modulation mode and diversity(More)

Both adaptive modulation and diversity combining represent important enabling techniques for future generations of wireless communication systems. In this paper, we present a new joint adaptive modulation and diversity combining (AMDC) scheme, termed as bandwidth efficient and power greedy AMDC. With this scheme, the modulation mode and diversity combiner(More)
We propose and analyze in this paper two new adaptive power controlled minimum selection generalized selection combining (MS-GSC) diversity schemes. The key idea behind these two schemes is to request the transmitter to vary its power level during very adverse channel conditions in order to communicate with the minimum required quality of service.
