Originální abstrakt

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.
