Does Fast Adaptive Modulation Always Outperform Slow Adaptive Modulation? [PDF]

IEEE Transactions on Wireless Communications, 2011
Link adaptation techniques are important modern and future wireless communication systems to cope with quality of service fluctuations in fading channels. These techniques require the knowledge of the channel state obtained with a portion of resources devoted to channel estimation instead of data and updated every coherence time of the process to be ...

Adaptive Spatial Scattering Modulation

IEEE Transactions on Wireless Communications, 2021
In this paper, two novel adaptive spatial scattering modulation (ASSM) algorithms, namely unequal transmission probability-based ASSM (UTP-ASSM) and equal transmission probability-based ASSM (ETP-ASSM), are proposed to pursue a better tradeoff between the computational complexity and spectral efficiency. According to available channel state information,
