摘要:
Peak power reduction in transmit chains of multi-band radiocommunication devices is performed. By using knowledge of the phase transformations which occur at the upconverter to determine how baseband signal samples will combine at the higher (upconverted) frequency, peak prediction and corresponding baseband signal modification can be performed in a way that reduces peak power of the combined signal.
