摘要: Characterized nonlinearities in a QAM transmission channel are removed by this linearizer, which selected bits from sequence of received symbols on both rails form the address PROM. Stored values represent Volterra expansion response channel, including nonlinearity, to symbol sequence. Symmetries allow same stored value be used correct AM/AM rail and AM/PM opposite distortion.
