Abstract
A method is disclosed for operating a mobile station (100) by determining whether there is a decreased probability of a presence of a transmitter (4) near to the mobile station that is transmitting on a frequency channel that is adjacent to a frequency channel being received from a serving cell transmitter (2) and, for a case where it is determined that there is a decreased probability of the presence of the transmitter, reducing the filter order of a baseband filter (224) of the mobile station and reducing the dynamic range of an analog to digital converter (225) of the mobile station for reducing mobile station power consumption. Reducing the filter order further beneficially reduces inter-symbol interference. In one embodiment the step of determining determines a speed of the mobile station, and correlates the speed with the probability of the presence of the transmitter such that at a lower speed the determination is that the probability is increased and at a higher speed the determination is that the probability is decreased. A measurement of adjacent channel transmitted power may be used as a verification. The speed is determined based at least in part on an output (184) of a…
