| Abstract: | The phase noise (PHN) is one of the primary factors that limits the achievable performance in many communication systems. Recently, the authors have proposed an effective "2-paths" PHN compensation scheme. The approach uses the information provided by an additional signal path added to the receiver front-end to better estimate the PHN. There are generally two types of PHN found in the literature: sta-tionary PHN and Wiener PHN. Previous results have shown the effectiveness of the "2-paths" scheme for stationary PHN. This paper addresses the applicability of the "2-paths" scheme for combating Wiener PHN. It shows that simple modifications of the “2-paths” approach work effectively for Wiener PHN as well. PHN estimation error and signal-to-noise ratio (SNR) after PHN compensation are analyzed. Simulation results for a 64-QAM system demonstrate the significant improvement over conventional approaches in the presence of Wiener PHN. | ||
