Abstract :
This paper presents a measurement system and experimental examples of error vector magnitude measurements on a wireless local area network receiver under several radio frequency impairments, with emphasis to local oscillator phase noise. An algorithm that cancels the phase and frequency carrier synchronization error is presented. Typical base band figure of merit are obtained under influence of these impairments. The described method allows the experimental calculation of error vector magnitude without a dedicated vector analyzer.
