Web19 mrt. 2024 · The receiver sensitivity is greatly reduced. For every QAM increment (e.g. 512 to 1024QAM) there is a -3dB degradation in receiver sensitivity. This reduces the range. Due to increased linearity requirements at the transmitter, there is a reduction in transmit power also when QAM level is increased. This may be around 1dB per QAM increment.
