[White paper] Radio Frequency Receiver Performance

Wireless communications require radio frequency (RF) systems to transmit and receive radio signals, making both transmitters and receivers vital for enabling innovative and efficient spectrum use. In the US, current regulation primarily focuses on transmitters, but adding restrictions to compensate for inadequate legacy receiver performance can be counterproductive. Improving receiver performance involves several key issues, such as those in technical considerations, co-existence between users of spectrum, and industry-specific policies.

This paper provides a timely technical analysis of receiver performance along with providing specific recommendations, contributions toward positive outcomes so industries can co-exist while making progress and aid government administrators in formulating policy.

Some key topics surrounding receiver standards in this 5G Americas report include:

• Basic problem of out of band interference (Effect of receiver filter & transmit signal)
• Current and previous work on receiver standards
• Other relevant studies, analyses, and memoranda
• Technical background (Receiver sensitivity, linearity, dynamic range, protection ratio, selectivity, blocking and overloading, spurious response rejection)
• Receiver impact in coexistence
• Industry and policy considerations
• Interference Limits Policy
• 5G Americas technical and policy recommendations
