Abstract
A wireless receiver detects signals received at two or more antennas, with each antenna coupled to an input receive chain. A switch is employed to couple selected input receive chains to one or more corresponding output receive chains during listening, coarse-detection, and fine-adjustment modes. At least one channel selection filter (CSF) is employed in each output receive chain, and the receiver employs sub-ranging. During idle mode, one antenna's input receive chain is connected to two or more CSFs to detect the packet. When the packet is detected, during a coarse-adjustment mode, the CSFs are reconfigured to couple each antenna's input receive chain to a corresponding output receive chain using low-gain signals. During fine-adjustment mode, the various gains are adjusted to be either high- or low-gain to maintain signals within the dynamic range of the corresponding CSFs.
