Modeling and Analysis of Phase Noise with Single-Channel Modeling and Simulation, primarily referencing the research paper "Effects of LO Phase and Amplitude Imbalances and Phase Noise on M-QAM Transceiver Performance." This includes MATLAB-based simulation approaches for phase noise generation and QAM system performance evaluation.

This paper analyzes the effects of phase noise on OFDM systems, revealing that phase noise induces both Common Phase Error (CPE) and Inter-Carrier Interference (ICI), significantly degrading system performance. To address these issues, we propose a CPE correction method based on the Mean Squared Error (MSE) criterion and an adaptive ICI cancellation technique using the Least Mean Squares (LMS) algorithm, which leverages the dominant interference from adjacent subcarriers. The implementation involves calculating CPE compensation factors through pilot symbol analysis and applying LMS-based adaptive filtering to mitigate adjacent-channel ICI. Simulation results demonstrate that our computationally efficient algorithm substantially enhances OFDM performance.
