Abstract: The disclosed systems and methods are directed to wireless receiver systems for neutralizing the effects of received RF blocking signals. The configurations presented herein operate to receive RF signals containing a desired signal and a blocking signal, a first module, in communication with the receive RF signals along a first signal path and configured to extract a specimen of the received desired and blocking signals, and a second module, in communication with the first module along a second signal path to receive the desired signal and blocking signal specimens. The second module is configured to produce a replica of the blocking signal based on the blocking signal specimen, generate an anti-blocking signal based on the blocking signal replica, and introduce the anti-blocking signal to the received desired and blocking signals in which the anti-blocking signal destructively interferes to neutralize the received blocking signal.

Abstract: A system and method for frequency-agnostic multiband aggregation of received signals is disclosed for use in high capacity communication. The system includes two up-conversion mixer stages and one down-conversion mixer stage, with SAW filter banks or other band pass filter banks used to select frequency bands of interest for aggregation based on configurable multiband combination settings. The method provides for the design of optimal multiband aggregation configuration settings.

Abstract: Methods and apparatuses for performing synchronization in a receiver of an analog code division spreading system are described. The method includes outputting a sampling point alignment signal to apply first time delays to align encoder code signals with a sampling point of an ADC The ADC is used to obtain digital samples of the orthogonal code-encoded analog signal at the sampling point. The method also includes outputting a decoder code alignment signal to apply second time delays to align decoder code signals with the digital samples. The method also includes outputting an orthogonal code alignment signal to apply third time delays to the decoder code signals and the encoder code signals, to maintain mutual orthogonality among the decoder code signals and to maintain mutual orthogonality among the encoder code signals.

Abstract: Apparatus for encoding a plurality of received radio frequency (RF) analog signals. The apparatus includes a plurality of pseudo-noise (PN) encoders for performing analog signal spreading and down-conversion. Each PN encoder is configured to encode a respective received RF analog signal using a respective one of a plurality of mutually orthogonal PN complex codes and to output a respective PN-encoded analog signal. The apparatus also includes a PN complex code source configured to provide the mutually orthogonal PN complex codes to the plurality of PN encoders. The PN complex code source includes a code generator for generating multiple mutually orthogonal PN codes, and a complex modulator for modulating the mutually orthogonal PN codes.
