Embodiments relate to updating spur cancellation at a victim integrated circuit (IC) in accordance with dynamic changes in the operating frequencies of an aggressor IC. The aggressor IC changes its operating frequencies at an update time that is determined in advance. The update time and the changes to the operating frequencies are shared with the victim IC. The victim IC dynamically updates the relationships between frequencies of local clock signals for the victim IC and the aggressor IC. The victim IC generates a spur cancellation parameter based on the updated relationships of local clock frequencies, the update time and the changes to the operating frequencies of the aggressor IC, and configures a spur cancellation circuit. In this way, the victim IC may perform effective spur cancellation despite changes in the operating frequencies of the aggressor IC and deviation of the local clock frequencies.

Dynamic configuration of spur cancellation

Disclosed wireless tunneling system includes two wireless tunneling apparatuses that communicate with each other through the wireless link. A local wireless tunneling apparatus is coupled to a local processing apparatus through a wired connection and a remote wireless tunneling apparatus is coupled to the remote processing apparatus through another wired connection. The two processing apparatuses bi-directionally communicate with each other through the wireless link using the two wireless tunneling apparatuses as if the two processing apparatuses were connected through a wired connection.

Full duplex radio in wireless tunneling system

A wireless tunneling system tunnels communications between a first host device and a second host device through a wireless link, while maintaining compliance of the communications between the first and second host devices with a wired communication protocol and operates in a power efficient manner. Two host devices may communicate with each other through a wireless link using the wireless tunneling system, as if two host devices were connected through the wired cable. The wireless tunneling system operates in one of a high power state and one or more low power states. In the high power state, the wireless tunneling system exchanges data at a higher data rate for tunneling. In the low power state, the wireless tunneling system disables power hungry components for conserving power.

A method and apparatus for adaptive beam-steering are disclosed. In one embodiment, the method comprises performing adaptive beam steering using multiple transmit and receive antennas, including iteratively performing a pair of training sequences, wherein the pair of training sequences includes estimating a transmitter antenna-array weight vector and a receiver antenna-array weight vector.
