Apparatus for compensating DC offsets, gain and phase imbalances between I-channel and Q-channel in quadrature transceiving system
(57) ABSTRACT A quadrature transceiving system for compensating a direct current (CD)
offset, again imbalance and a phase imbalance between an I-channel signal and a Q-
channel in a quadrature transmitting system is disclosed. The quadrature transceiv ing
system includes a transmitter for detecting a DC offset, again imbalance and a phase
imbalance by using an average of a data aided signals included in a RF transmitting signal
and compensating one of the I-channel and the Q-channel based on the detected …
