A Measurement-based Behavioral Model for I/Q RF Modulators

This article describes a nonlinear behavioral modeling technique for application to I/Q modulated communication channels. The model data was gathered by independent measurements of an I/Q modulator and amplifier, using vector signal generators and anal...
The W-CDMA standard expresses transmit quality in terms of EVM and ACLR, and receive quality in bit error ratio (BER). These quality measurements are simple scalar numbers representing a very complicated system. Modern communications channels (still) consist of a number of concatenated functions such as baseband (BB) processor, DAC,...
