Modeling and Analysis of Phase Noise

This research focuses on the modeling and analysis of phase noise through single-channel modeling and simulation, with primary reference to the paper "Effects of LO Phase and Amplitude Imbalances and Phase Noise on M-QAM Transceiver Performance." The study emphasizes analyzing the impact of phase noise on M-QAM transceiver performance. We employ single-channel modeling and simulation techniques to construct phase noise models, typically implemented using MATLAB's communication toolbox functions such as `comm.PhaseNoise` for phase disturbance generation and `qamdemod` for evaluating symbol error rates under noisy conditions. Through investigation of the referenced literature, we gain deeper insights into how local oscillator (LO) phase/amplitude imbalances and phase noise degrade M-QAM system performance. This research holds significant importance for enhancing the performance and stability of M-QAM transceivers. Future work may explore phase noise mitigation techniques using digital signal processing algorithms like Kalman filtering or phase-locked loop (PLL) simulations to reduce performance degradation. In summary, phase noise modeling and single-channel simulation constitute critical steps in studying M-QAM transceiver performance, providing essential foundations for understanding and improving digital communication systems.
