Abstract

A novel functional nonlinear high power amplifier model for radio communication system simulations is used to study spectrum regeneration of a nonlinearly amplified π/4-DQPSK signal. Simulated adjacent channel power has been compared to measured results, and a very good resemblance is found. This together with a satisfactory intermodulation behaviour in a two-tone test simulation verifies that the proposed model is applicable to accurate adjacent channel power prediction in radio system simulations
