Abstract

To achieve higher spectral efficiency and more efficient usage of channel resources, adaptive modulation can be used jointly with diversity combining, or with power-loading, or with both selection diversity and power loading. We derive closed-form expressions of the performance of multi-channel systems with the conventional adaptive modulation and hybrid schemes, in terms of the spectral efficiency, the average bit error rate and the outage probability. Numerical results show that average modulation with selection-combining and power-loading (AMSP) offers higher spectral efficiency and lower outage probability than other schemes, and is more reliable in low signal to noise ratio (SNR) regions.
