Abstract

In a multimode transceiver, the transmitter for one communication standard induces a large interference on the receiver for another one. When this large interference passes through the inherently nonlinear receiver Front-End (FE), it introduces Cross- Modulation (CM) distortion. Increasing the FE linearity to lower the CM distortion leads to unacceptable power consumption for a handheld device. Considering the continuous increase of digital computation power governed by Moore's law an attractive alternative approach is to digitally compensate for the CM distortion. An existing CM compensation method is tailored to single-mode transceivers and requires an auxiliary FE. By using the locally available transmitted interference in the multimode transceiver, we propose a CM compensation method which requires no additional analog hardware. Hence the power consumption and complexity of the multimode transceiver will be reduced significantly.
