Co-Simulation of Nonlinear Components and WiMAX System Using a New Parameter

Error Vector Magnitude (EVM) is related to nonlinear distortion of the Low Noise Amplifiers (LNA) that are used in the Worldwide Interoperability for Microwave Access (WiMAX) communication systems. A co-simulation of the components and system using the S-parameter was not effective for the design of the EVM. We proposed a new parameter, which we called P-parameter, as a nonlinear model of the EPHEMT transistors that were used in the LNA. The cosimulation results by the nonlinear model were close to the measured value.
