Abstract :
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 structure are adaptively determined based on the fading channel condition and error rate requirement. We accurately analyze this AMDC scheme in terms of processing power consumption, spectral efficiency, and error rate performance. Selected numerical examples show that the proposed AMDC scheme satisfy the target error rate requirement while achieving high spectral efficiency with low processing power consumption
