Abstract:This paper presents a low-complexity adaptive feed-
forward I/Q imbalance compensation algorithm. The feed-forward so-
lution has guaranteed stability. Due to its blind nature the algorithm is
easily incorporated into an existing receiver design. The algorithm uses
three estimators to obtain the necessary parameters for the I/Q imbal-
ance compensation structure. The algorithm complexity is low due to
1-bit quantization in the estimators. Simulations show that the compen-
sation algorithm is able to attain an image-rejection ratio (IRR) of up to
65 [dB] under various imbalance conditions.
