WSRD Workshop IX: "Radio Receiver Systems: R&D Innovation Needs, and Impacts on Technology and Policy"

May 5, 2017

Principles of co-existence and interference tolerance are often overlooked and under-exploited in today’s radio receiver systems. For example, a receiver’s ability to accept wanted signals or reject unwanted signals impacts the quality of the information transmitted. The Wireless Spectrum R&D Interagency Working Group (WSRD) held a workshop, “Radio Receiver Systems: R&D Innovation Needs, and Impacts on Technology and Policy”, on May 5, 2017 at the National Science Foundation, Arlington, Virginia. The workshop addressed various signal reception topics including technology advances for receivers, transmitters, filters, antenna design, signal processing techniques, and policy issues.

Even as additional radio frequencies are being available in the U.S., such as the move to open up several millimeter-wave bands, the nation’s radio spectrum continues to get more congested. With the continued proliferation of bandwidth hungry devices, including the IoT, the need for innovation in radio receiver technology is believed to be an important step toward making spectrum coexistence more successful. For example, recommendations have been made in reports coming out of the FCC’s Technology Advisory Council, and the European Union recently published a new Radio Equipment Directive (RED) that includes guidance on receivers. The overall goal is to help build trust between Federal and non-Federal operators and spectrum users. Hence, co-existence within the spectrum bands and with adjacent bands, for both licensed and unlicensed users need to be effective, efficient and trustable. While focus has been on the transmitter side of the radio system in the past, focusing on the receiver systems early in the next generation technology development process has been identified as an important step in assuring interference tolerance.

This workshop provided a forum for information exchange and the identification of relevant radio receiver systems research and development opportunities. WSRD members across multiple federal agencies will use information gathered from this workshop to develop recommendations for their agency-specific research agenda...
