Abstract
Devices, systems, methods, and non-transitory media facilitate image rejection for a radio frequency signal with a wideband carrier. Wideband signals from a device may be analyzed, the wideband signals corresponding to a wideband channel. Each wideband signal may correspond to a sinusoidal electrical signal with IQ amplitude and phase modulation. An in-phase component (I) of a wideband signal may be determined. A quadrature component (Q) of the wideband signal may be determined. Based on the determined I and Q, a wideband IQ imbalance may be determined. A scalar error based on the wideband IQ imbalance may be obtained. The scalar error may be mapped to a vector error plane. Orthogonal error vector points that are based on the mapping may be determined. The wideband IQ imbalance of the device may be compensated based on adjusting an IQ setting of the device with the orthogonal error vector points.
