  • Memory polynomial based digital predistorter
    Patent number: 9160280
    Abstract: The memory polynomial based digital predistorter utilizes a cluster-based particle swarm optimization (PSO) technique and has an embedded model-size estimator. The PSO technique and model-size estimator efficiently find the dimensions and accurately estimate the coefficients of the memory polynomial based digital predistorter for improved linearity of a power amplifier.
