Abstract:The error vector magnitude (EVM) is extensively applied as a metric for digital transmitter signal quality compliance in modern communication systems. In cooperative communication, signal carrier frequency and symbol rate are predicted, and the reference signal can be recovered from demodulated symbols directly. However in non-cooperative communications, the signal carrier frequency and symbol rate are estimated. Since the demodulation and EVM are very sensitive to symbol rate, we focus on the EVM of non-coope… Show more
