This paper aims on three different behavioral models with memory for radio frequency power amplifiers. These models are based on the principle of Volterra series, which were simulated in the Matlab-Simulink environment and implemented on a DSP-FPGA Altera Stratix III board. The MPM, Hammerstein and Wiener models were compared based on the distortion curves AM-AM and AM-PM of a RF-PA 10W through different...
This paper presents the design methodology of a complete digital pre-distortion system that enables the power amplifier linearization. This system employs the memory polynomial model for its realization. The performance of the linearization is validated by using an LTE carrier signal in the band of 10 MHz. This integrated solution is capable of linearizing any real power amplifier from measurements...
