This white paper gives an overview of the critical issue of phase noise in satellite communication systems and its impact on channel capacity. Phase noise is a significant contributor to Signal-to-Noise Ratio (SNR) and as such is an important determinant of channel capacity in any communication link. Phase noise, originating from various sources such as satellite transponders and ground equipment can significantly degrade the performance of satellite links, leading to reduced throughput and increased error rates. Understanding and mitigating phase noise is vital for optimizing satellite communication networks and ensuring efficient data transmission.
