ABSTRACT:
The present invention provides architectures and methods which use multiple radio receive chains in mobile devices to provide enhanced performance, such as when acquiring and maintaining network access. A plurality of receive chains simultaneously perform signal level measurements across one or more measurement cycles. The number of RF channels upon which measurements are performed may be determined adaptively/dynamically. One or more criterion may be used to set signal level thresholds. If a measured signal for a given channel fails to satisfy a threshold, then that RF channel may be removed from the network acquisition process. If a measured signal for a channel exceeds another threshold, then that channel may be employed in further network acquisition processes, such as identifying potential beacon signal channels, verifying beacon signal channels and synchronizing the device to one of the beacon channels.
