• An approach to the correction of I and Q imbalance in the time domain is discussed. The correction coefficients are resolved in the time domain by injecting a standard sinusoidal test signal. Compared with the methods developed by Li (see Radar Engineering. The Sea Press, Beijing, 1999) and Churchill (1981), who obtained the correction coefficients in the frequency domain by the discrete Fourier transform (DFT), our method decreases the large amount of calculations. The formulas of residual deviations after correction, which depend on the ratio of signal energy- to-noise power density (2E / N/sub 0/), are also discussed.
