摘要: Aspects for measuring IQ path mismatch in signal modulation are described. The aspects include estimating a transmitter form of gain and phase response I Q paths sharing receiver path, source. Further included is compensating the difference using digital FIR filter. Iterative estimation utilized filter tap parameters during compensating.
