Abstract
A mobile communication device (100) includes a receiver (102) which is normally shut off when the mobile communication device is idle. Upon the arrival of a paging time slot to which the mobile communication device is assigned, the mobile communication device turns on the receiver and begins receiving a composite signal including frequency diverse subchannels. The mobile communication device measures the delay spread of the subchannels (406). The receiver then adjusts the receiver on time for the next time slot based on the delay spread of the present time slot.
