Using nonlinear functions, the output signal of the PA can be linearized, mitigate distortions, and be effectively optimized. When using various operating channels and varying time, temperature, and PA nonlinearity, the DPD must adjust. In order to increase the power efficiency of...
This finds applications in the upcoming 3GPP NR systems which have designed short uplink control transmissions for latency constrained applications and for embedding phase tracking reference signals in the uplink transmissions of mmWave systems. A naive approach to multiplex RS and data in a single ...
