Abstract:
A method for interference reduction is described. The method is implemented in a wireless device. It is determined that a page is going to be received via a secondary receiver. It is also determined that a digital-to-analog converter (DAC) image from a transmitter will cause interference with the secondary receiver when the page is received. A sampling frequency of the DAC for the transmitter is changed so that there are not any DAC images from the transmitter that will cause interference with the secondary receiver.
