Abstract

Bit error rate (BER) is an accepted figure of merit in the industry for the characterization of transmission link quality and communications systems in general. While useful as a conceptual figure of merit, it suffers from a number of practical drawbacks that compromise its value as a standard test in manufacturing or maintenance. This paper discusses the use of error vector magnitude (EVM) and its relationship to BER to develop a foundation that will help in formulating and implementing a sound and cost-effective test strategy for component, sub-system and system test in communications systems, such as mobile cellular, satellite and wireless data networks
