Patent ID: 7729677

Claim:
A receiver in a wireless network, comprising: a first filter configured to filter a packet received at each of two or more antennas; a diversity circuit configured to: measure a first signal strength of the packet received at a first of the two or more antennas after the packet is filtered by the first filter; responsive to the first signal strength being greater than a threshold, select the first of the two or more antennas for a duration of a packet reception otherwise measure a second signal strength of the packet received at a second of the two or more antennas after the packet is filtered by the at least one of the FIR or IIR filters; compare the first signal strength to the second signal strength; and select the second antenna if the second signal strength is greater than the first signal strength otherwise select the first antenna; and a second filter having a latency higher than the first filter and configured to filter the packet after the diversity circuit selects the first or the second of the two or more antennas.
