چکیده
The paper presents our experimental workplace currently built-up for testing of power amplifier linearization algorithms. After a brief introduction into linearization techniques using predistortion, a measurement configuration together with a brief description of its individual components are presented. The paper also presents the first experimental results. On the example of the QPSK modulation, the nonlinearity polynomial model has been evaluated. This workplace has been realized in order to test the operation of the real predistorters on digitally modulated signals. Key-Words: power amplifier, digital modulations, linearization

متن کاملFPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
