Closed Loop Radio Interference Cancelation

Technology Benefits

qAdapts to any condition of the noise which is part of the signal driving the adaptive digital filter. qVersatile method that can be applied to in various forms. qReduce interference at various stages in the receive chain. qMaximum possible signal-to-noise ratio.

Detailed Technology Description

University of California researchers have developed a closed-loop, digitally controlled and analog interfaced method for cancelling interferences from a set of RF transmit chains to a set of RF receive chains. This novel analog-digital method is no longer limited by transmission noise. The invention can be used to recover a weak signal in the presence of a stronger signal. This method can be used in parallel or in serial for better combined effect. The final structure of the system is such that all interference and major noise sources have a zero or minimum net contribution to the received digital signals.
