摘要： A method of predistorting a waveform for input to an amplifier includes receiving information associated with the waveform, the information comprising a modulation configuration of the waveform. The method further includes predicting a chain model for the waveform based on the modulation configuration. In addition, the method includes predistorting the waveform for input to the amplifier, based on the chain model, an ideal waveform, and target output power. An apparatus is also provided for predistorting a waveform for input to an amplifier.

摘要： Techniques for correcting for memory effects of a transmitter are described. In an exemplary design, a receiver obtains input samples including a desired signal transmitted by a transmitter having memory effects. The receiver performs nonlinear equalization on the input samples to obtain first equalized samples, performs linear equalization on the input samples to obtain second equalized samples, and determines output samples based on the first and second equalized samples. The nonlinear equalization corrects for the memory effects and nonlinearities of the transmitter and possibly nonlinearities and memory effects of the receiver. The receiver may jointly determine coefficients for both linear and nonlinear equalization based on an adaptive algorithm. The receiver processes (e.g., demodulates and decodes) the output samples to recover data sent in the desired signal by the transmitter.
