How does PAPR reduction improve power amplifier efficiency?
5G’s Orthogonal Frequency Division Multiplexing (OFDM) brings with it a major design challenge, namely an inherent wide dynamic variation between a signal’s peak and the average power. The peak-to-average power ratio (PAPR) leads to inefficient transmission performance. That’s because the OFDM waveform is created by the sum of multiple sinusoidal signals that can exhibit constructive…
External GPU digitally down converts captured RF signals
