Abstract:
Methods and apparatus for interference cancelation in a radio frequency communications device are described. In various embodiments a signal to be transmitted in converted into an optical signal and processed using an optical filter assembly including one or more optical filters to generate an optical interference cancelation signal. The optical interference cancelation signal is converted into an analog radio frequency interference cancelation signal using an optical to electrical converter prior to the analog radio frequency interference cancelation signal being combined with a received signal to cancel interference, e.g., self interference. The optical filter assembly can include a large number of taps, e.g., 30, 50, 100 or more. Each tap may be implemented as a separate optical filter or series of optical filters. Delays and/or gain of the optical filters can be controlled dynamically based on channel estimates which may change due to changes in the environment and/or communications device position.

Claim (Index 2):
An interference cancelation method for use in a communications device, the method comprising:\n operating a radio frequency signal to optical signal converter having a radio frequency input to receive a radio frequency signal to be communicated and to generate there from a first optical signal; operating an optical filter assembly to filter said first optical signal to generate a second optical signal; and operating an optical to radio frequency converter coupled to an output of said optical filter assembly, to generate a radio frequency interference cancelation signal from the second optical signal output by said optical filter assembly.
