摘要:
This study examines the distortion characteristics of the QMBOC (Quadrature Multiplexed Binary Offset Carrier) modulation signal. The QMBOC ideal signal creation formula extends the digital and analog distortion model suited for QMBOC by mathematical modeling, based on the 2-OS distortion model and BOC distortion model. The legend is then generated using a simulation platform. The inconsistency in the weight proportion of the distortion of the in-phase and orthogonal components of the QMBOC signal is attributed to the γ power factor of the sig...
