IQ imbalance image compensation in multi-carrier wireless communication systems

A method in a wireless communication terminal, the method comprising:

• receiving, at the terminal, an OFDM symbol carrying an aggregated carrier including a first component carrier and a second component carrier, the OFDM symbol including a reference signal, wherein the first component carrier includes a first subcarrier carrying a first symbol of the reference signal and a second subcarrier carrying a second symbol of the reference symbol, and wherein the second component carrier includes a third subcarrier carrying a third symbol of the reference signal and a fourth subcarrier carrying a fourth symbol of the reference signal;
• measuring leakage from the first, second, third, and fourth subcarriers;
• receiving a signal on the aggregated carrier;
• and
• compensating for leakage of the signal from the first component carrier to the second component carrier based on the measurement of the leakage of the reference signal.
