Phase Noise Impact on Satellite Uplink and Downlink Channel Capacity

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.

Understanding Shield Effectiveness

Shielding, or screening effectiveness, is essential to the safe operation of electric vehicles (EVs). There was a time when the noise generated by the spark plugs firing in an internal combustion engine caused an annoying buzz when listening to the AM radio. Circuit designs have since evolved, and this issue was eventually resolved, but now the issue is back.
