Abstract
There is provided an apparatus comprising means for receiving a first signal on at least two frequency carriers, wherein two of the frequency carriers are separated by a frequency gap and are of unequal bandwidth to each other, means for determining a power of a second signal located in the frequency gap, means for determining that the power of the second signal is above a first threshold and means for applying an in-phase/quadrature (IQ-)imbalance compensation algorithm to the received first signal to suppress an image signal from the second signal in at least one of said two of the frequency carriers.
Claims22
An apparatus comprising at least one processor, and at least one memory storing instructions which, when executed by the at least one processor, cause the apparatus at least to perform:
- receiving a first signal on at least two frequency carriers, wherein two of the frequency carriers are separated by a frequency gap and are of unequal bandwidth to each other;
- determining a power of a second signal located in the frequency gap;
- determining that the power of the second signal is above a first threshold;
- and
- applying an in-phase/quadrature imbalance compensation algorithm to the received first signal to suppress an image signal from the second signal in at least one of said two of the frequency carriers.
(canceled)
A method comprising:
- receiving a first signal on at least two frequency carriers, wherein two of the frequency carriers are separated by a frequency gap and are of unequal bandwidth to each other;
- determining a power of a second signal located in the frequency gap;
- determining that the power of the second signal is above a first threshold;
- and
- applying an in-phase/quadrature imbalance compensation algorithm to the received first signal to suppress an image signal from the second signal in at least one of said two of the frequency carriers.
A non-transitory computer readable medium,
- comprising instructions wherein the instructions, when executed by at least one processor of an apparatus cause the apparatus to at least perform:
- receiving a first signal on at least two frequency carriers, wherein two of the frequency carriers are separated by a frequency gap and are of unequal bandwidth to each other;
- determining a power of a second signal located in the frequency gap;
- determining that the power of the second signal is above a first threshold;
- and
- applying an in-phase/quadrature imbalance compensation algorithm to the received first signal to suppress an image signal from the second signal in at least one of said two of the frequency carriers.
