Third Order Intermodulation Distortion Effect on The Constellation Error in RF Transmitter of IEEE 802.11a WLAN System

In wireless data communication, an advanced nonlinear distortion analysis is required in order to see its effect to the performance of a Radio Frequency (RF) front-end system. This technical paper therefore, reports the effect of third order intermodulation (IM3) distortion on the constellation erro...
