    Innovation #3: Receiver Performance Specifications

    3.1 Executive Summary

    The growing movement to encourage spectrum sharing will be a significant enabler for cognitive radio systems. However, existing spectrum users have a reasonable expectation that their systems operation will not be impaired by new in-band and adjacent band users. Historically, this has been managed through a variety of standards and regulations primarily focused on transmitter parameters, sometimes with unexpected consequences. The Forum believes that long term the entire range of both transmitter and receiver characteristics must become an integral part of spectrum regulation and management. Specifically, adding focus on regulating receiver performance can bring much benefit in terms of spectrum efficiency through such regulation while at the same time reducing risk for new market and new technology entrants.

    3.2 Application

    • Identification of the critical receiver parameters required in order to enable spectrum sharing systems in existing bands.
    • Capability of current and future receiver front end technologies
    • The standards required to support the regulation of receiver specifications.

    3.3 Description

    The critical receiver parameters required in order to enable spectrum sharing systems in existing bands must be developed looking at a historical view of how receiver performance has impacted spectrum regulation. Potential examples from the US include the 800MHz Public Safety rebanding and Lightsquared terrestrial LTE at 1.5GHz.

    The current and expected receiver performance criteria for existing systems must then be evaluated for effective protection. This requires a survey of existing systems across the government, public safety, satellite and commercial markets. A roadmap of receiver performance then needs to be developed, as well as an evaluation of the potential impact of evolving communication systems on incumbent solutions.
