Quantized Digital Amplification with combination over the air - Achieving maximum efficiency on communication links between long range UAVs and satellites

Uplink high throughput is essential to assure good situational awareness in Unmanned Aerial Vehicles (UAVs) mission. For that purpose larger bandwidths should be combined with the maximum possible spectral efficiency at the uplink. This leads to the use of multilevel broadband modulations with high Peak-to-Average Power Ratio (PAPR) values that may compromise the power amplification efficiency of ...
