Abstract: Disclosed herein are methods and systems for embedding a supplementary data channel in LTE-based communication systems. One embodiment takes the form of a process that includes obtaining a primary data signal. The primary data signal includes a given symbol, and the given symbol includes primary payload data prepended with a given cyclic prefix. The process also includes obtaining supplementary payload data. The process also includes generating a modified primary data signal at least in part by replacing an initial portion of the given cyclic prefix with a subset of the supplementary payload data. The process also includes outputting the generated modified primary data signal for transmission via an air interface.

Abstract: A communication device includes a receiver that is capable of canceling in -channel interference. The receiver includes an antenna for receiving a wireless signal comprising in-channel components and an out-of-channel component, wherein the in-channel components comprise a desired component and an in-channel interference component. A first filter of the receiver filters the wireless signal by blocking at least a portion of the out-of-channel component to produce a first signal comprising the in -channel components, and at least a second filter of the receiver filters the wireless signal by blocking at least a portion of the in-channel components to produce a second signal comprising the out-of-channel component. An in-channel interference estimator of the receiver generates an in-channel interference estimation signal based on the second signal. And a combiner of the filter combines the first signal and the second signal to at least partially cancel the in-channel interference component of the first signal.
